I made a tentative gitified Alexandria repo, up at
http://github.com/nikodemus/alexandria
Would moving to git inconvenience people, aside from one-time switch-related issues?
I personally find git *much* more convenient to work with -- but this is very likely just due to knowing it far better than Darcs.
This is not about relative merits of Darcs and Git, but about convenience for people involved. I'm pretty sure either one is plenty "good enough" for Alexandria per se.
