Can't think of any that won't.  Some may not care (e.g. because they
only use syntax-ppss and not font-lock), but I can't think of any where
we'd need/want to specify different values for the various packages that
could use such info.

I look at it from the exact opposite viewpoint: the packages that need
to set those boundaries may not even need/want to use syntax-ppss (or
font-lock) themselves, so it'd be completely wrong for them to have to
set a syntax-ppss-* variable (or a font-lock-* variable).
