If a cafe is an amenity=cafe only if A, B and C, you would have to
revisit each week, anyway, to check that it's still A, B and C.

My point is that I like the approach of tagging A, B and C, instead.

Yes...hence why I like the approach of tagging what you mean...

I disagree. If a "cafe" is a concept that's easily defined and
internationally consistent, that's great, and telling the consumer
there's a "cafe" is great. But if it isn't, then telling the consumer
there's a "cafe" puts MORE burden on them to work out what that means,
than specifically telling them there's "a place you can get coffee and
snacks, and...".

You don't have to render everything.

That'd be great! I should mention that I'm not suggesting we
completely scrap the amenity=* tag - but if we're finding it hard to
agree on a definition of amenity=cafe, that would suggest to me it's
not a good tag! Can we agree on a definition for
amenity=food_or_drink_outlet, used in combination with the specifics?
Much more likely, I think.
