[RFC] cgit in git?

Background: I've been asked by the fedora project how to package cgit.
The problem is basically that cgit is designed to be statically linked
with a specific git release (i.e. libgit.a and xdiff/lib.a).

When manually building cgit from a tarball this isn't a problem:
'make get-git' will download the required git sources from kernel.org.
But the buildsystem/policy used by the fedora project does not allow
network access during package builds, and since it is quite unlikely
that the git package always will match the exact release needed by the
cgit package, I only see four options:
1) the fedora project makes a 'git-for-cgit' package containing the
needed release of the git sources
2) the cgit release tarballs includes the needed git sources
3) the cgit sources are subtree-merged into git
4) cgit is modified to link against libgit2

Option 1 seems unlikely to happen since such a 'git-for-cgit' package would basically require the fedora project to support two git packages.

Option 2 is doable but still requires the fedora project to support two git packages (but now the 'git-for-cgit' package is hidden inside the cgit source tree). The good thing about this option is that it only requires some minor modifications to the cgit releases.

Option 3 would solve the problem for the fedora project but is not for me to decide - it might become an extra maintenance burden on the git maintainer and community.

Option 4 is the correct solution but not a very practical one; it's currently hard to predict when libgit2 will be ready for general (c)git use.

Personally I'd love for option 3 to happen, hence this rfc.
