Yes, it existed before. It's a bug but not a regression. But many of these
:core packages were primarily used as libraries supporting other packages,
not do much as user-facing, command-providing, UI-enhancing packages.

From what I've been seeing in the Eglot bug tracker there is a very
significant number of people using third-party package managers to install
and upgrade Eglot (straight, elpaca, ...)

I always tell them to report problems sweet package-install instead of
these managers, as I've seen more than my fair share of problems created by
these other managers.

My experience and the internal traffic reports tem me Eglot is a popular
Emacs package and people are not satisfied with just any old release. If
this isn't fixed, it'll be heaps of text to tell people how to upgrade. Not
the end of the world, but really awkward.

There is certainly code in Emacs 29 that allows upgrading Eglot or other
core packages but it's buried deep in that odd workflow. If the code for a
M-x package-upgrade, as Stefan suggests, is simple, then i think it should
be added to emacs-29.

Alternatively, there could be some kind of 'package-bugfixes' non-:core
package in elpa.git that adds this new command. Asking people to install
that package first is still easier than guiding then through that odd
workflow.
