[Tagging] relevance of water taps as opposed to fountains

[Davidoskky]

> Similarly the tap that is part of a drinking fountain cannot represent the whole fountain, hence it shouldn’t be in “competition” with the fountain tag, it could be added as a property like tap=* but adding it as man_made to the amenity (which is supposed to represent the whole feature) would just be a misrepresentation and misleading.

+1 from the wiki page for example I would not tag these two as water_tap:

While I would tag this one as a water_tap:
