In bug#74145 I suggest that it is time to change the default of
`lexical-binding` to t. Clearly this is a breaking change, but only for
those files which:
- Don't have a `lexical-binding` cookie.
- Have code which happens to behave differently under the new dialect
(such code is not rare, but a lot of code works identically in the
two dialects).
I believe by the time Emacs-31 will be released, such files will be
uncommon, and it is easy to fix them (either by adjusting he code, or
by slapping a `lexical-binding` cookie).

+1 It's time.
Anecdata, but: a lot of the random Emacs packages I encounter in
the wild lately have `lexical-binding` cookies already (and
usually to t anyway). Most recently
https://github.com/kmonad/kbd-mode/blob/master/kbd-mode.el, for
example. No doubt there are also many that don't, but I think
knowledge about the new dialect is diffused widely enough now that
when Emacs' default switches over, some user of a given package
will quickly recognize what's going on and submit the appropriate
change to that package; in a few cases I have done so myself.
Best regards,
