Well that's easy to do since that's the way it is in my tree.

The only reason for the new_ prefixes and the config options was to
make it easy for people to test them.

I didn't sent it only as a bkpatch, a following mail had the patch in
diff format.

Anyway I'll repost them as per you suggestions...
