There's no direct relation between moving packages between
repositories and excluding them from the release tarballs.  We can
have one, but not the other.

What is the advantage of having a more lightweight tarball?  Disk
space is no longer at premium, and Emacs is a relatively small package
by modern standards.

Yes, but then installing a tarball gives me Org and Gnus etc., even if
they are slightly outdated.  If we go your way, I don't have them at
all, and need a live, reliable, and uncensored network connection to
get them; until I do, my Emacs is crippled or might not even start at
all.  That's a net loss.

When I install XEmacs, I always want the "sumo" package, for that very
reason.

There are only disadvantages here.  You add conditions that, if they
are not satisfied, will interfere with the upgrade.  It's a nuisance
for no good reason.
