Well, I for one like to take a middle ground between what works now and
what we will probably need in the future.

Vending machines are mapped entirely according to this model, using
vending:*=* . By the logic we used for shop=*, it should have been
amenity=bread_vending_machine or amenity=vending_machine + bread=yes. The
vending:* tagging style makes it easier to process all sorts of data, and
easily allows further extension.

I wouldn't say we should change shop tagging styles to that. I was merely
taking the stated position that fuel shops should follow that structure to
its logical conclusion. And I'm starting to think we might actually have to
consider it to avoid ever further cluttering of the shop types.
