We could maybe help you if you told us to what part of the code you refer

The code is what it is for many reasons including the fact that dpkg -S

Exactly, that's the thing I'm referring to.

Should I read it as "the only legal situation where it returns multiple packages are diversions (the rest are errors)" or "the majority of situations ... are diversions", ie. does it make sense to return multiple packages in the absence of diversions?

not specified (in the doc at least). In practice you might get a mix of
both dependencies and to avoid any problem the packaging of the diverting
library should simply stay compatible to the one of the official library
(i.e. generate the same dependencies).

Yes, but I think this is unattainable. Especially when doing transitions, you're not likely to have both packages in sync.

I just wanted to know if it would be OK for dpkg-shlibdeps to use only one package for a library (eg. in case of diversions, use dpkg-divert to find the right one) and fail in case of ambiguity.
