On first thought this sounds good, but I think one would end up having
to sync the actual state of things in two places. What if package-vc.el
had a place where it stored all available commands? Then the use-package
integration could just use that. I think it would also be easier to have
this codified somewhere, rather than having to check the manual every
time.
