<div>I just got alerted that you added a paragraph on the wiki
Page <a
href="https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access-Restrictions)"
moz-do-not-send="true">OSM_tags_for_routing/Access-Restrictions</a></div>
<div>in which you state:</div>
<div><br>
</div>
<div>"
Note that explicit tagging of access repeating what
following tables imply may be still useful. For example bare
<tt dir="ltr" class="gmail-mw-content-ltr"
style="background:rgb(238,238,255) none repeat scroll 0%
0%;font-size:1em;line-height:1.6"><a
href="https://wiki.openstreetmap.org/wiki/Key:highway"
title="Key:highway" moz-do-not-send="true">highway</a>=<a
href="https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath"
title="Tag:highway=path" moz-do-not-send="true">path</a></tt>
may mean either "surveyed and all defaults apply" or "mapped
from LIDAR, not surveyed, may be private". In contrast <tt
dir="ltr" class="gmail-mw-content-ltr"
style="background:rgb(238,238,255) none repeat scroll 0%
0%;font-size:1em;line-height:1.6"><a

<p>That addition from Mateusz seems reasonable to me - he's just
alerting people to how things might get mapped, and how to make
things clearer. Also "may still be useful" is not telling people
to add e.g. "motor_vehicle=yes" to all primary roads (something
unlikely to be useful).<br>

<p>It doesn't matter what you think J Random Mapper _should_ do;
what they _actually_ do is what is important (and I'm someone who
uses access=unknown more than most).</p>
