Speedups would be nice, but I think this sounds like a very big change
to make to such a central system (that I think many third-party packages
rely on) at this point, so I'm leaning towards it being in Emacs 29
instead.

Xref is an "ELPA core" package. As soon as we make this change on master and bump the version, it will affect the third-party packages right away. Not when Emacs 29 is released, year(s) later.

On the flip side, we can make the change now, bump the version, and be reasonably certain that when Emacs 28 comes out, the third-party packages are already updated for the version that comes with it.

It's also the most reliable way to work out the kinks that I know of.
