FWIW, I think the TAB/C-i, RET/C-m, ESC/C-[, DEL/C-? confusion should be
fixed by really decoupling the two.

Maybe one way to do that is to have a `function-key-map` fallback from `[?\C-i]`
to `[TAB]` (so `?\C-i` and `tab` would be "equal partners" both of
which default to falling back to the new `TAB` key).

You say "for instance" above, but which confusing cases are there other
than the four TAB/C-i, RET/C-m, ESC/C-[, DEL/C-? special cases?

Truly inspiring.  A have a question: how would you define "ambiguous"?
