I almost feel guilty for bring them up, but only almost because it has
been illuminating. In mentioning them, apart from trying to be as open
as possible, I was also thinking about how to be more specific about
the type of brewery say, without introducing keys for every type of
drink under the sun, i.e., allowing
craft:brewery=ale;wheat_beer;fruit_beer, whilst still allowing a
simple craft:brewery=yes. I've seen this approach recommended on the
basis that it "limits entries in the global namespace". Does anyone
know of a current implementation that actually takes advantage of
namespaces in this sense?

That is nothing, my current favourite is
http://wiki.openstreetmap.org/wiki/Proposed_features/access_restrictions_1.5

With beautiful constructions like:
access:vehicle?school_zone.maxspeed=30
access:motorized+electric?hov_time.occupants=1+
