While I'd actually like it if we required leakproofness for what we
ship, I agree that we shouldn't blindly assume that add-on data types
are always leakproof and that then requires that we explicitly verify
it.  Perhaps an argument can be made that there are some cases where
what we ship can't or shouldn't be leakproof for usability but, ideally,
those would be relatively rare exceptions that don't impact common
use-cases.

Thanks!
