Right. I'm still looking at Martin's message from this morning. I had
assumed that all callers of find_module() were in importlib, but
obviously that's not correct.

Are there any callers of find_module() outside of the standard library?
That would be reason to invent a new API, instead of trying to reuse
find_module().
