Hard to say.  Our experience with the standard contrib modules is that
it really isn't much additional trouble; but perhaps more-complex modules
would have more interdependencies between functions.  In any case,
I fail to see the need for basing things on a catalog lookup rather
than embedding API version numbers in relevant C symbols.
