    I do believe that uncontrolled should be deprecated in favour of
    marked, which iD already did. I also agree that marked/unmarked was
    a good improved in the crossing scheme, but it should be cleared on
    the wiki page, which seems to favour the uncontrolled tag.<br>
    About your considerations:<br>
    <br>
    1 - That depends on the country. For example, in Portugal, all
    crossings have right of way over vehicles. So, marking a crossing is
    the same whatever the type you map (besides unmarked, of course)<br>
    <br>
    2 - I think there area already tags for all that. You can check them
    here under "Additional tags":
    <a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Key:crossing">https://wiki.openstreetmap.org/wiki/Key:crossing</a><br>
    <br>
    3 - Same as previous point.<br>
    <br>
    4 - In the same page, under "Mode of transport"<br>
    <br>
    5 - There's also reference to that in the page, but I agree this is
    not very clear and is scattered in several wikis, like this:

        <div dir="ltr">Hi,</div>
        <div dir="ltr"><br>
        </div>
        <div dir="ltr">crossing has been a very poor tag because it
          seems to be the kitchen sink for all the questions pertaining
          to crossings...
          <div>Many of the attributes that get values in "crossing" are
            potentially overlapping and not mutually exclusive, causing
            a lot of confusion and poorly tagged crossings.
            Nevertheless, specifying crossings is very important because
            it's a highly contested street region.</div>
          <div><br>
            <div>The crossing tag has held many values that may overlap,
              and we should once and for all split out all these
              different tags so we can be mapping what we mean and mean
              what we map.</div>
            <div>Questions we should be answering when mapping a
              crossing:</div>
            <div>1) How is this shared space controlled? A crossing is a
              high risk environment where traversal is shared between
              cars and pedestrians (they are of unequal footing). So the
              type of 'control' and 'right of way' in that space is
              important to specify. 'uncontrolled' is a very bad tag in
              this direction because it has an actual legal,
              non-intuitive meaning and many mappers mistakenly think a
              crossing that has no traffic signal is uncontrolled- so
              that's a really bad tag.</div>
            <div>crossing_control= ?</div>
            <div><br>
            </div>
            <div>2) How is the space demarcated? A crossing may be
              demarcated by a number of different ground markers, it may
              also be physically demarcated from other street
              environments by raised footway, tactile paving or
              reflectors.</div>
            <div>crossing_ref=? (for visual demarcation)</div>
            <div>additional tag for physical demarcation?</div>
            <div>(I'm in disagreement with those saying it's superfluous
              or hard to tag this way)</div>
            <div><br>
            </div>
            <div>3) How can a pedestrian call up the signal and how can
              they sense whose right of way is currently allowed?</div>
            <div>Is there a call button? Does it chirp, speak out, 
              vibrate?</div>
            <div><br>
            </div>
            <div>4) who is sharing the way (also a bicycle crossing,
              animal crossing, etc)?</div>
            <div><br>
            </div>
            <div>5) How is the space connected to the rest of the
              transportation layer? to the pedestrian layer? Crossings
              should really only extend from curb to curb, so that the
              kerb could be properly tagged for its physical
              characteristics. The habit of extending crossings all the
              way into and overlapping with sidewalk spaces is a pretty
              bad idea considering those are protected pedestrian spaces
              and have very semantic meaning to pedestrians than the
              high risk crossing environment.</div>
            <div><br>
            </div>
            <div>I think crossing=marked/unmarked was a really good step
              in the direction of getting resolution and refinement on
              at least one of these questions above. We should now move
              together to refine the definitions and values for these
              other questions...</div>

                <div>I do crossings as crossing=marked/unmarked. I
                  believe software should be able to identify if the
                  crossing has a stop sign or traffic signal. Pedestrian
                  walk/don't walk are low on my radar right now.</div>
                <div><br>
                </div>
                <div>I stopped using zebra since they seemed more
                  appropriate for a crossing in England than where I
                  live in the US. Crossing=marked/unmarked the only
                  thing I see where I map them. </div>
                <div><br>
                </div>
                <div>BTW - I believe in the US hitting a pedestrian in a
                  marked crossing is illegal most everywhere. In some
                  cities, drivers seem to believe they have the right of
                  way over pedestrians, even if they are in a marked
                  crossing. </div>
                <div><br>
                </div>
                <div>In another country I've spent some time in, cars
                  definitely have the right of way over pedestrians. </div>
