Or upgrades existing ones.

Two layouts have to be supported. It's just a question of who has to
support them. In my scheme, it's core emacs, in your scheme its
individual package developers.

Probably in most cases, it's not a big deal, and it will happen

I think the semantics of understanding how to copy the package files to
the legacy (er, proper) locations is pretty much the same as package.el
already has just for loading them.

Oh, and, all of this copying has to happen *before* we generate
loaddefs.el which means it has be done with bootstrap-emacs, which is a
tricky bit of the build to be fiddling with.
