Ah, too much work.

Having libraries where the exported functions have signature seems
more desirable than no signatures (documentation benefit, at least).
So a tool could just print a warning "No type signature for
_export-name_". This would be an effective social obligation to
encourage people to add signatures to exported functions. Also other
developers could see the library wasn't using export signatures and be
cautious about depending on it themselves.

Best wishes
