This proposal asks the ADs and WG Chairs to do more work and I perceive lack of resouces in that area to be the single biggest reason for I-Ds to fail to progress as fast as they might. Putting more load on the critical path can only make things worse, for the work as a whole. Some favoured I-Ds will progress faster but overall, RFCs will take longer to appear. In this vein, I have commented before how progress in the IETF tends to take place in three bursts, in the course of each year, and that if only we had a way of bringing the three pauses to life, then progress would be much improved. Quality would almost certainly also improve, since data would not get lost or forgotten in the pauses. This month, most WG mailing lists seem to be in a mega-pause (I keep checking the archives to see if I have been accidentally unsubscribed!): that is the real problem.
