At the moment it isn't. My original plan, if you remember, to have emacs
core load ELPA packages with package.el. This requires some minor
re-working of package.el (so that the -Q doesn't block them), some
Makefile fiddling and introducing some standards to test file location
in ELPA, so that it's possible to run ELPA tests from within core.

The alternative proposal is, essentially, to copy files into the Emacs
core build structure and move from there.

Reading the discussion reinforces my feeling that the latter is the
wrong approach, because it reinforces a distinction between packages on
ELPA and packages in core above and beyond the location that they are
stored and versioned. I can't see the advantage of doing this.

I will probably try to work a little further on my package.el solution,
although there seems little enthusiasm for this as the way forward.
