These days "focus on the extension" would be more helpful. Maybe
we could check to see if all the functions referencing a given .so
belong to the same extension, and if so complain about that extension?
I think there's a reasonable argument that functions that don't
belong to any known extension should be printed individually,
because more than likely the user's gonna have to clean them up
manually, as we saw here.
