Unfortunately, client signaling the version is nasty to do in ways that
wouldn't cause current servers to hang up or do other undesirable things.

git://: Git-daemon will hang up[1] if it receives command it won't
understand (and one can't add arguments either).

ssh://: Commands are NAKed in non-standard ways (e.g. Gitolite vs. shell)
and one can't add arguments.

file://: That's easy.

CONNECT: The helper needs to be told that v2 is supported (helper doing
the rest).

Maybe with git://, one could hack the stuff in similar way as virtual
hosting was added. But that won't work with SSH (nor one can use environment
with SSH).

[1] And there is no guarantee that the server end of git:// is git-daemon.
There's at least one git:// server implemetation that responds to unknown
commands by ERR packet followed by hangup.
