Two different issues. I agreed with you on the ATC aspects several messages ago. RNP AR was intended to solve difficult terrain issues and typically at airports where ATC couldn't care less such as Rifle, Colorado and Bishop, California.
But, along comes an airline with more money than insight and thinks they will save a few gallons of Jet A every leg with RNP AR at high traffic locations.
Now that it is obvious even to them that it isn't working they are whinning to the highest levels of the FAA. That, of course, will get them nowhere.
I believe that very limited use of RF legs on SIDs and STARs will eventually prove to be useful, once most of the operators, including business aviation, are approved for non-RNP AR RF legs. But, that is it. Forget RNP AR IAPs at high traffic locations except special cases like down the river at KDCA.
