They have that control now. No package will start itself, unless the
user invokes it.

This is just going to be far more complex if we off-load large
portions of Emacs to elsewhere: there will be more combinations of
different versions to consider and support.

That burden is what allows users to be sure their packages will work
with future versions of Emacs. Take that away, and the QA problem I
was talking about will rear its head.

If we are going to tie specific versions to specific Emacs releases,
then what is this all about? Why all the overhead? What do we gain?

Yes, and whenever I need to install some package from CPAN, I end up
installing dozens of its dependencies first. Do we really want that
for Emacs users? I don't.

That is the slippery slope I don't want us to take. Not even the

I tried to explain how.

Packages that are not in core get much less attention from the core
maintainers. It starts with the fact that I don't see them compiling
on my machine each time I build Emacs, so any warnings I might have
seen and taken care of, if only be letting the maintainer know, will
be lost for me. It goes on with me not watching commits to ELPA
packages, so I don't have a chance of timely catching problematic
code. Etc. etc. -- the Emacs QA doesn't cover unbundled packages.

I'm not telling you anything -- that "please" was there for a reason.
And how's that different from your suggestion, anyway? If you can
tell us that "the other way around would have been infinitely more
useful", why cannot I tell you what I did?
