My concern with this change is that it eliminates a strong motivation for people to track me down and make sure I’ve quickly reviewed any actions requiring my participation. I agree that the current system puts too much onus on the person who’s responsible for tracking people down, but the new system eliminates the motivation to make sure people providing “passive consent” have had an opportunity to review RFCs before they advance.
My ideal system would have a timeframe for participation to address the issue @withoutboats experienced. During this time, the system would nag me to participate, giving me a clear deadline to reply, therefore eliminating the need for a person to track me down and ensuring that I don’t inadvertently slow the process down indefinitely.
