So what did you mean by "the tarball will include the same file as
before in emacs/lisp"? which file will that be, and how is it
different from what will be in emacs/elpa?

Still confused: how is that different from the first alternative,
where you said the file will be in emacs/lisp?

I actually like the other alternative, because people will want faster
startup, and because it makes no sense to let users disable bundled
packages.  If we think people will want to disable a package, we
shouldn't bundle it.
