Nope, doesn't work, doesn't do anything to those packages.  I wish it
did, of course.

I also don't understand why this is using separate, but repeated logic
from package-update.  What is the difference between "upgrade" and
"update", if any?  Is "upgrade" more powerful?

BTW, I also noticed that Eglot's version on Emacs 29 is garbled.  I had
wanted 1.12-emacs29 to somehow show that it is Emacs 29 specific.  But
version-to-list doesn't like it and the package shows up as version
"nil" in package--builtins.  Will just change it to 1.12.29, which is
less perceptible but works fine (none of this makes any difference to
this bug, of course).
