It's also true that if a sizable group of network operators were to actually deploy source address validation (thus proving that it really is a reasonable approach and doesn't carry too much operational or vendor implications), then it would be quite reasonable for those operators to bring the results to NANOG and get it recognized as a best current operating practice for networks of similar design/purpose.
