Great! Thanks for your responses, especially for the background, which
explains a lot.
Basically, The scale has changed drastically.
"Mind the scale" became my mantra at OSM!
That's why I think everybody should at least try some micromapping
(close to z=19) - it shows you the whole mapping process from a
different side! Things like general "mapping highways for router" or
lack of some features (land with a "hole" inside, that may be many
different things which are not yet mapped or even don't have tagging
scheme) starts to be instantly apparent.
Any town sized amenities with an area to denote grounds (school,
hospital, golf course, etc) should move to Landuse to follow the other
major landuses.
+1! Seems rather logical to me to mark area as landuse and leave
"amenity" for buildings or points inside.
Theres some holes in that idea, but it is better to patch those holes
than keep letting amenity get stuffed with more and more disparate
tags.
There are many holes in early ideas, but it's natural and the only way
to fix them is through discussion and practice.

Now it gets really interesting: given that more people than just us 3
;-P wants to have more coherent tagging system and approves such
migration, how should it be done? I guess we have no procedures for such
important and big changes yet. We're ready for adding new features, but
not so much for changing already existing - especially well established
ones - and I think we will really need it one day (even if not this
time).
One way I can think of could be by massive, automatic adding a new tag
(amenity=car_wash -> amenity=car_wash + shop=car_wash) to let people
remove the old ones gradually, because it could be less intrusive than
any kind of conversions. It will be not always possible, because some
objects has already some shop=* tag added as a primary/secondary
feature. On the other hand it would help some objects tagged as
amenity=feature1;feature2 to become amenity=feature1 + shop=feature2 (if
feature1 is not considered to be a shop in a new take and feature2
should be shop indeed). The downside is it could take years to complete
and in the meantime everybody using our data should implement additional
code to deal with both forms, because there's no clear point to jump to
the new scheme and leave the old cruft in the dust.
It would be probably better to reach some consensus and make the
conversion in one go, since the change is pretty straight (like
"s/k=amenity/k=shop/g" for some objects). It has another pitfall,
however: OSM is rather big ecosystem than a single project, so we should
send the message that we plan to make such change, but I don't know what
channels should we use to make it really heard. It also means we accept
possible breaking some stuff outside, because there always be some not
actively maintained services which people still use. But at the same
time that would also mean we're able to evolve rather than simply grow
and it would make people aware that they need to check the news once in
a while.
What do you think about this problem?
