I don't think keeping support for git:// is too onerous at this point
(especially because it should make the jump to protocol v2 with the
rest). But it really is a pretty dated protocol, lacking any kind of
useful security properties (yes, I know, if we're all verifying signed
tags it's great, but realistically people are fetching the tip of master
over a hijack-able TCP connection and running arbitrary code on the
result). It might be nice if it went away completely so we don't have to
warn people off of it.

The only thing git:// really has going over git-over-http right now is
that it doesn't suffer from the stateless-rpc overhead. But if we unify
that behavior in v2, then any advantage goes away.

I do agree we should have _something_ that is easy to spin up. But it
would be wonderful if git-over-http could become that, and we could just
deprecate git://. I suppose it's possible people build clients without
curl, but I suspect that's an extreme minority these days (most third
party hosters don't seem to offer git:// at all).
