Oh. Yes, generally we do try to use these and make the patches minimal.
I am Cc-ing Jack Morgenstein who did the lion's share of work implementing
the backport.
I guess what you are saying is that we had missed quite a bit and they could
still be made smaller - in this case, would you care to post improved
patches?

Of course, it is unfortunate that these proposals for sweeping changes
come at such a late stage in the game - we are close to code freeze.

But let's see the code and we'll be able to decide whether this change
seems safe.
