Do we need that?
Are there examples, where the we need building:use? For most cases we 
already have corresponding tags that would double the building:use:
shop=*, a lot of values in amenity=*, the aeroway=hangar example...
I don't think building:use ever is useful instead of or additional to 
the corresponding fitting "real" tag; but perhaps you (or anybody else 
can give examples of usages, where such a tag is missing or where there 
are reasons not to use/invent one.
