Right, although I wouldn't necessarily say that the former doesn't have a proper API, but rather that it has a Unix-oriented API. That leads to performance issues on e.g. Windows but on Linux I'm not sure there's much of a difference. > It would also be pretty bad for closure size: > > --8<---------------cut here---------------start------------->8--- > $ guix size guile-git | tail -1 > total: 106.6 MiB > $ guix size guile-git git-minimal | tail -1 > total: 169.8 MiB > --8<---------------cut here---------------end--------------->8--- > > It=E2=80=99s also not clear concretely how we=E2=80=99d add that dependen= cy.

We could consider replacing the guile-git dependency with another library built directly on top of git-minimal, and have this be a dependency of Guix. Not ideal though, and not really scalable either: we can't just add every VCS as direct dependencies. From=20what I've seen, people are now scaling back on their use of libgit2 because of the impedence mismatch and are resorting more and more to git plumbing. From a pragmatic point of view, I'd prefer the latter, since it is more stable and feature-complete.
