Thanks for the patch. Unfortunately, I do not understand the use for
it.
You see, git’s repository format _has_ changed in incompatible ways a
few times already without any corrusponding bump in the repository
format version. Examples: the addition of packed refs, and the
addition of alternative packed object formats. Maybe that is
unfortunate, but it has not caused any major breakage I know of. Part
of the problem is perhaps that different features are added at the
same time and it is not immediately obvious which one deserves the
higher repository version number.
So the GIT_REPO_VERSION feature ends up being either a failed
experiment or an important futureproofing measure. Either way, we
won’t know what it means it gets incremented. ;-)

I think any successful git-based source package format will be based
on pack files rather than checked-out repositories. That is, I
suspect if anything will work as 4.0 (git), it would be git bundle
based, partially because bundles are meant to be usable with the
endpoints having vastly different git versions.

Isn’t that V in the error message?
