That's true.  Exactly the same as package-install. It will not
reinstall over another one.

But that doesn't change anything.  In Emacs 26/27/28 from scratch
package-install and use-package _will_ rev up Eglot to whatever is the
newest version.  In Emacs 29 it won't.

In fact deleting Eglot and restarting Emacs the config run again is what
I suppose the most common upgrade method (since there is no
package-update in Emacs 28).

Other than that, think CI scripts, dockerfiles, VMs, or just the
casual user who trashes the packages dir to get a fresh set when
looking for a bug (like I do, and multiple people I've interacted with).
