All those differences disappear when we are discussing core packages.
Which is my only focus in this discussion.

I very much hope it doesn't stay that way for core packages.

This is a red herring. Emacs releases are less frequent because Emacs
is a large collection of packages, and thus the period required for
its stabilization is much longer. A single core package can apply
stability criteria and still not go anywhere near the Emacs release
frequency. It does need more effort on the part of the package
developers, but the effect on the release frequency will be minor.

"Two years" because you think the release frequency of Eglot will be
slowed down to such abysmally low value? As explained above, I think
this is not going to happen, so there's no need to assume this will be
the outcome.
