We would need to eventually have at least one backend that we know
will play well with different Git implementations that matter
(namely, git-core, Jgit and libgit2) before the feature can be
widely adopted.
The first backend that is used while the plugging-interface is in
development can be anything and does not have to be one that
eventual ubiquitous one, however; as long as it is something that we
do not mind carrying it forever, along with that final reference
backend. I take the objection from Shawn only as against making the
sqlite that final one.
