IMHO, No - I don't like the idea of using separate/duplicate features
(e.g. an extra node) to describe something at the same physical
location.

Ideally, you would tag the building as simultaneously:
amenity=school (or townhall) AND
amenity=place_of_worship

...but this isn't possible because we require a 1-to-1 key-value
mapping (not really sure why, but that's the way it is).

So right now, I see four remaining options, IMHO all pretty crappy and
unsupported:

1) mash it into:
amenity=school;place_of_worship

2) mash it into:
amenity:school=yes
amenity:place_of_worship=yes

3) use two separate relations (one amenity=school and one
amenity=place_of_worship) that both have the building as the sole
member. John might have further thoughts on this [IMHO very hacky] use
of relations.

4) tag the primary function (so at least one well-established
amenity=* tag remains), then tag supplementary functions:
amenity=school
place_of_worship=yes (plus maybe place_of_worship:opening_hours=sunday, etc.)
