It's not necessarily so trivial.  For example, the main OSM style is run by
backend that has surprising limits due to database design.
However a rendering engine that's iterating through objects could take:

amenity=toilets;drinking_water
fee=no
opening_hours=24/7
toilets:position=seated;urinal


And expand it to:

amenity=toilets
fee=no
opening_hours=24/7
toilets:position=seated;urinal

amenity=drinking_water
fee=no
opening_hours=24/7
toilets:position=seated;urinal


But quickly you have tag pollution and it is not clear semantically which
tag is the "main tag", and which tags refer to which amenity.
Somewhat clearer is:

amenity=toilets
drinking_water=yes
fee=no
opening_hours=24/7
toilets:position=seated;urinal


Which would expand to:

amenity=toilets
fee=no
opening_hours=24/7
toilets:position=seated;urinal

amenity=drinking_water
