This is pretty much what use-package does actually. It's an odd package,
in that the main entry point is a macro. Nowadays, it's even needed at
runtime iff you compile your .emacs.

I don't think so, no. It's easy to write a new macro which adds these
timings and expands to `with-eval-after-load'

I haven't checked how ELPA load-paths work. Unlike John, though, I don't
sync my ELPA directory; actually I tend to delete it periodically. My
.emacs auto-installs any packages I need.
