Softfork signaling improvements

Hello. I've seen Greg make a couple of posts online (https://bitcointalk.org/index.php?topic=1033396.msg11155302#msg11155302 is one such example) where he has mentioned that Pieter has a new proposal for allowing multiple softforks to be deployed at the same time. As discussed in the thread I linked, the idea seems simple enough. Still, I'm curious if the actual proposal has been posted anywhere. I spent a few minutes searching the usual suspects (this mailing list, Reddit, Bitcointalk, IRC logs, BIPs) and can't find anything.

Thanks.
