At this point I don't know. I knew of the change because I usually like to 
watch Paul's talks and watched his LCA talk not too long ago. I got the 
impression that he started working on the change in the last year, so it 
probably doesn't go back too many kernels.

I should be able to look at this some this weekend. It might be beyond my skill 
to do acceptibly, but I'm interested in giving it a shot. rc1 won't be out 
until the end of the weekend so there is a bit of time yet.
