For 1.7, I would recommend leaving "dav props" (aka wcprops) in the
working copy library. At a minimum, for backwards compatibility
purposes. But I think we just don't want to get into ripping that out
right *now*. Let's ship 1.7 first.

I would certainly not be opposed to considering the removal of dav
props from wc in the 1.8 timeframe. I suspect that since we always
intended them to be a *cache*, then we can probably remove their
storage without a problem.
