Why not wikify that database?

The rough idea is the following: there is not "the" list of definite 
map-features, but we have a single server with user-accounts where every 
application developer could leave his own map feature list (or reuse another 
list). Then the server's job is just to match each feature list against the 
osm database and report the incoherencies to both the mapper and the 
application developer.

From the application developer's point of view, it's no additional work 
because you have to define anyway which tags you want to use.

From the mappers point of view, you can get on a single web page a complete 
feedback about how your tags would impact on all the applications, instead of 
tediously gathering the information from several sources.

And there is still you central instance needed (beside a database server with 
a not-so-complicated software).
