The core part of "Packaging" in the elpa.git world basically means:
- Start the package's main file with ";;; <name> --- <description>"
- Sprinkle a few ";;;###autoload"s.
- Add a "Package-Requires:" (when needed).

This is very straightforward and can be done from the very beginning
of development.

After that, something needs to create the *-pkg.el and *-autoloads.el
files, but we know how to do it mechanically ("make" in elpa.git takes
care of it, for example).

So what's missing here I think is just some extra support to
transparently do this "make" step (probably not with "make", of course)
for those packages not installed via package.el.

I said "partly overlaps".  So it doesn't all overlap (and in those parts
that don't overlap, the correct/incorrect packaging is not relevant).

If I didn't consider use-package useful/interesting I wouldn't
participate in this discussion.
