Yup, that would break lots of existing code, indeed, and in subtle
enough ways that people would go crazy.

Luckily, there's no "100% ideal" way buffer-local and scoped bindings
can interact.  All choices suck in some circumstances, so there's really
no good reason to lament the current choice: it's no worse than
the alternatives, AFAIK.
