you are pointing me to an open ticket for which there might be good
reasons _not_ to realize it in order to prove your statement "That
definition hasn't been true since use of surface=* was expanded beyond
highways for things like golf bunkers" ?

Come on, it "was" never expanded, you would like it to be expanded.

Don't know. I don't actually care for beaches if they are tagged
surface or landcover, but I think that it would be easier for
everybody to just use one key instead of 2, and I think that landcover
is generally better suited for all kinds of values and surface is not
yet established so it wouldn't be a big "change".

this is not only about rendering, it is about the meaning. If you
wanted to make a map of a golf course, you would maybe want to
distinguish between casual sand and a bunker.

to unify the mapping, to make the data interpretable. This has in
second place to do with rendering and is not "tagging for the
renderer". Any kind of data evaluation should be possible.
