No I don't see it as a mistake. It is not a fake religion, it is an unambiguous catchword. "multi*" 
is used in OSM for facilities that serve an unspecific number of different purposes, sport=multi is 
another example.
For the religion case, it was discussed on this list already [1].

religion=multifaith is used already nearly 400x, Mateusz was not proposing it, he was just about to 
refine the definition.

There are some cases with 2-3 dedicated religions where the semicolon system is already being used. 
They are as rare as such institutions are. Clarifying this specific situation does not mean to copy 
that everywhere.

Apparently they are infrequent, thus semicolon is better than value-keys.

 From my perspective, Mateusz, go ahead as you said.
