Your solution doesn't "give me what I want".  If I add 'eglot-update' it
will work as a single command on every Emacs version from Emacs 26.3
onwards.  This new command you're proposing is for Emacs 29 only (and
will presumably be deprecated soon).

So "what I want(ed)" is for `M-x package-install RET eglot` to keep
working smoothly as it did up to here and forever onwards.  That's want
many package managers do (the "install" verb upgrades, or offers to
upgrade).  That not being possible, I had settled for a decent working
`M-x package-update RET eglot` instead.

So this is "what I want": smooth user experience with no new commands or
at least simple ones that don't require understanding emacs dev
concepts.

I think 'package-update-core-package' is just unfortunate, because the
regular user doesn't care what the heck is core, and can you blame her?

I can't stop you from adding it, of course.  Have you thought how it
should behave when the package is no longer a core package, i.e. has
already updated?  I.e. should 'package-update-core-package' update a
non-core package in certain situations?  If so, then we're inches away
from 'M-x package-update-any-package', which is just a fixed `M-x
package-update` as I proposed.  If not, then it's really quite strange
to have to run one command for one update and another command for the
next one.

I have to ask (though I can guess the answer): may I add 'eglot-update'
anyway to emacs-29 as a no-brainer shortcut in the meantime?
