I don't think it's a tangent. Emacs out of the box already favours ELPA,
and does not enable other archives. The default for additional mechanism
for loading external packages would be at least as restrictive --
i.e. out of the box, Emacs would only use this additional mechanism for
ELPA.

I would assume that anything else we added would also be usable with
other package archives. So, the GNU distribution of Emacs might, for
example, not ship with org-mode, but auto-install and then autoload it
on first usage. The same facility could be used by, for example,
spacemacs to auto-install and then auto-load any of the packages that
spacemacs provides.

It would be possible to make the use of an auto-install functionality
work straight-forwardly only with ELPA, but I can't see why you would.
