I agree with Christoph -- every tag used in OSM data must be documented --
otherwise it has near-zero value.. Actually negative value because it
confuses people -- some might want to delete it, but they don't know if it
is useful, so they just leave it there almost indefinitely.

In an ideal world (not limited by the current tooling), the person adding a
new tag should type in an explanation why they are adding it at the same
time it is added.  The tools should also show the user what other similar
tags are available (based on the name and the typed in description), in
case the user is making a mistake and the needed tag already exists.

If we agree on this vision, lets work on achieving that -- we can discuss
implementation details, and I will be happy to participate in that.
