I like the idea that we could kick git into a mode that applies the
behaviors we're talking about having in 2.0, but I'm concerned about
one aspect of it.  Not having these behaviors until 2.0 hits means
we're free to renege on our decisions in favor of something better, or
to pull out a bad idea.  But once we insert this knob, I don't know
that we have the same ability.  Once people realize it's there and
start using it, it gets harder to back out.  I guess we could maintain
the stance that "the features are not concrete yet," or something like
that, but I think people would still get upset if something changes
out from under them.

So, at the end of the day, I'm just not sure it's worthwhile to have.
