I'm just wondering whether it makes sense to fix 2) if we're not fixing
1), and I don't think fixing 1) is a good idea (it'd make the function
massively slower).

Instead I'm wondering whether we should just fix the doc strings here to
not mention `find-function-source-path' in `find-function' (etc), so
that the doc string matches the implementation, and instead mention
`find-library-name' (in the doc string) for your use case.
