I'd be mostly OK with the purely visual fontification change, but
if there is an accompanying change in syntax it breaks some
of the tools available to fix the situation, that is a bad thing.

Sure, and in languages such as elisp or ruby, CC-mode's approach
would be useless: you would still see the blinking. In languages
such as python and js even more complex to implement (some
strings can be multi-line and some not).

I do understand the suffering of those that don't use e-p-m. It's
one of the reasons that I started using it.  But if you don't want
to for any reason, I posted a patch to jit-lock.el in the split thread
that should  reduce if not eliminate the blinking you suffer.

I invite you (or anyone) to try it and post feedback. It will work
for any major mode, and won't introduce any breakage in
the C-M-stuff.
