It should still be possible to distinguish key-bindings to C-i
(i.e. TAB) and C-S-i (i.e. S-TAB), provided the underlying terminal
allows it, obviously.
Does your code still allow this distinction?

Agreed.  `insert' and `char-to-string' have no business messing
with keys.

I think this was just an accidental misfeature and would should not
preserve this kind of backward compatibility.  I can't imagine how it
could break any existing elisp package, and if a user used that in the
past, there are plenty of alternative ways to get the same result in
a saner way.
