Yeah, I've done this. I know a single building that houses Christian and
Jewish communities with distinct names and contact info, neither more
prominent than the other, so this seems like the correct solution.

I've done this too, when it appears that a smaller church has set up
shop inside a larger one. (And the sub-tenant doesn't have to be a
church either -- commonly I've seen schools, childcare, social
facilities, charity shops, etc. inside church buildings. There's even a
famous story of a destroyed:amenity=bureau_de_change.)

This is clever, but I don't think I'd recommend it.

  - It might be hard to verify that that no portion of the building or
grounds is used exclusively by one community or the other.
  - Not all churches have grounds. (Of course you could actually use the
building's nodes for all three ways, but I don't see this as an
improvement on the two-place-of-worship-nodes solution.)
  - I generally prefer to map grounds as landuse=religious and save the
place_of_worship tags for the location where the worship services happen.
