It goes further that that, by the way: the few times I have to interact
with an Hg or Bzr repository, I don't use Hg or Bzr, I use Git.

Back when I was using Bzr instead, I did the same: I used Bzr to access
Svn, Hg, and Git repositories.

[ Some tools go even a step further and decouple the tool used locally
  from the format used locally, so you can use the Brz tool on a local
  Git clone IIUC.  ]

So `package-vc` doesn't need to support all VCS because we can rely on
bridges to decouple the tool used locally from the format of
the repository (tho, those adapters/bridges tend to be a bit fiddly,
admittedly).

Good question.  I don't think there's any such thing in MELPA, at
least :-)

The only non-Git repositories I know of are either Hg or Bzr.
I wouldn't be surprised if there's some package stored in Svn
somewhere, tho.
