I'm talking only about Eglot, not in general.  I believe I've stressed
that point already.  So what I said or did or asked to do regarding
other packages or other places in Emacs is not necessarily relevant
for this discussion.  The decisions about these issues are always on a
case by case basis, so you cannot compare different cases and expect
them to yield the same decisions.

Of course I can.  But once again: if Eglot 1.14 is not stable enough,
then why do we recommend users of Emacs 29 to update their bundled
Eglot to v1.14?  This is inconsistent: if 1.14 is not stable enough to
be in Emacs 29, we should only recommend it for users of Emacs 30.

I already explained this inconsistency more than once.  Why do you
keep bringing it up time and again?  You might disagree, but why do
you insist that I accept what I perceive as inconsistent logic?  Just
let it go and accept that we disagree about this.

No, it doesn't require any forks.  It requires more cautious
introduction of new features into Eglot on master.  And yes, it's
extra effort.  But IMNSHO, users will benefit, so in my book it's
worth it.
