You bring up a lot of the same questions I have about the new working copy design. I assume the developers have considered all of this carefully and are making the best choices they can. I plan to wait until 1.7 is released and then just see what's happened. I understand some (all?) of this is already implemented in trunk so you can of course build from there and see how it works already.
