[Tagging] RFC - A broad look at fountains

[Davidoskky]

Is this proposal functionally any different from the water outlet 
proposal? https://wiki.openstreetmap.org/wiki/Proposed_features/Water_outlet

I'm alright with using a name different from fountain since a lot of 
people disagree on that name.

By doing all this you're effectively deprecating amenity=fountain; 
that's strange to me.

I would not tag decorative fountains as tourism as those are not 
necessarily there for tourism; you have fountains in hidden places that 
have never seen a tourist...

Moreover, this would require retagging a lot of objects, and it cannot 
even be done mechanically because you'd end up mistagging the fountains 
which are not decorative.
