My vote, after thinking about it, is to move it to the core.  That would
turn it into an Emacs facility, rather than an external package.  The
closest analogue is SMIE, which also lives in the core.

PL is a library for building other packages, so I think users don't
really care where it lives.

It's also unlikely existing packages will switch to use it, so new
packages can require it *and* a new Emacs. If a compatibility version is
needed, I would put the compatibility PL with version 24.999 in the GNU
ELPA or elsewhere, so the built-in PL with version 25.x or newer wins.
But I'd rather not maintain two versions.
