No--it's in a Draft state and not ready for review. Not sure whether @showeimer still wants to drive the development/verification or you want to take over if it's still relevant?

Hey sorry, just seeing this. I wasn't able to actually verify that this policy works due to not having a way to test it; you guys are welcome to copy this over or close it out.
