Should there be some kind of diagnostic if you have an @abiPublic definition that is never referenced by any @inlinable function? I can imagine that there might be tools to check that a new build of a module doesn’t break binary compatibility by verifying that you didn’t remove any @abiPublic symbols, but what if you never meant to and never needed to export that symbol in the first place? How do we prevent that from happening?
Perhaps a diagnostic like this would cause problems if you started with an @inlinable function that called an @abiPublic function and then in a subsequent version of your module you modified the @inlinable function such that it no longer calls the @abiPublic function. You would still need to keep that @abiPublic function to support clients that had inlined the old version, right? Maybe this could be built into the hypothetical binary compatibility checker. If there is no previous version or if the previous version didn’t have the symbol and it’s never referenced then it’s an error. Would that work?
