FWIW, this is what Mercurial's "named branches" do. Instead of having
branches point to commit, each commit says what branch it belongs to.

One drawback of this approach is that the branch name is part of the
commit and can't be changed without changing the commit's sha1. Hence, a
local, private, branch name becomes permanent the day it's merged
upstream.

(for completeness: Mercurial also has essentially Git-like branches,
but they call this "bookmarks")
