The reason we should apply the noquote stuff now before head get's stable is exactly the fact that
a) It is a major thing that needs to be adopted throughout the system, and better now than later.
b) Noone expects head to be stable. Adding the noquote thing will most likely not break pages that haven't been broken before.
c) The people working on noquote are (AFAIK) not people that would be involved in getting the HEAD more stable anyway.
Looking forward to see it implemented.
