Interesting - not something I've ever encountered. I have encountered
issues with indexing (the effects of the referencing columns not being
indexed, that is), but never with the number of schemas that referenced
it. Have I (and my co-workers) just been overly careful?

Whoa there everybody!
While the answer is quite correct, of course (I read the FM years
ago), what has not been raised is the danger of allowing reference to
multiply unhindered across numerous schemas.
Be very careful if you choose to do this, otherwise, without a little
care, you may manage to lock your entire database solid with
conflicting FKs!
We did, learned our lesson, and now reference is ONLY permitted within
the one corporate schema.
