I don't really understand what "backward-incompatible change" you are referring
to.  Or are you simply saying that *any* change is "backward-incompatible"?
It's ok to break things that are already broken.

What *do* people use quotemeta for if not for regexes??

I do not at all like that it behaves differently depending on the
whether the dodgy UTF-8 flag is on.

Currently, it quotes all 128 code points between 128-255 if and only
if the UTF-8 if off.  I do not consider this reasonable, desirable,
or in any fashion useful.

I see three possible changes in that code-point range.

    (1) Don't quote them at all, because Perl doesn't use them *yet*.
    (2) Quote all 63 \W code points in that range.
    (3) Quote all 18 Pattern_Syntax code points in that range.

Choices two and three beg the question of why there but not higher up.
And the answer to that question is because Perl isn't using those yet.

Which again leads back to choice one.
