I suppose part of the question is what sort of way we treat it? In my mind,
considering the current way lexical scope is seen in Emacs (used everywhere in
modern elisp, not on-by-default because that would break compat, is my
impression). I think it would make sense if this eventually ends up with a
“globally enabled everywhere by default” setting, which is why I think a
defcustom may be the best fit.

Mmm, something generic for backend-specific modification sounds like a good idea
to me.

All the best,
Timothy
