I don't think we can get a single set of criteria across core packages.

E.g. Org is developed externally, has its own community of significant 
size, and does split off release branches (with additional testing, I',m 
guessing).

Eglot, OTOH, is developed only here, with no additional release workflow 
other than what MELPA/GNU ELPA historically provided: collect up some 
features/fixes, bump the Version header, and push a new release out to 
the users. The lack of extended testing period is made up for with the 
capability to push out a new fixed version overnight. That's why the 
difficulty in upgrading to the latest version (for Emacs 29 users) is 
going to hurt.

BTW, if you recall the threads before Eglot was added, I was against 
that, and one of the things I cited is an LSP client has inherently high 
development velocity. Maybe the LSP community will settle/mature/stop 
adding features one day, but it's not there yet.

Note that that suggestion comes with a fix to eldoc which you so far 
have rejected for emacs-29.
