Would be a great topic for pgconf.eu in June (pgcon moved to Vancouver). Too bad the CfP is over, but there's the "unconference" part (but the topics are decided at the event, no guarantees).
Did you mean pgconf.dev in May (which has the unconference), or pgconf.eu in October (which doesn't have an unconference, but the CfP will open sometime in the - hopefully near - future)?
Yeah, I meant May. Sorry :-( Too many conferences around that time, I got confused.
That being said, submitting this into the pgconf.eu CfP is a good idea too. It's just that it seems like a nice development topic, and the pgcon unconference was always a great place to discuss this sort of stuff. There are a couple more topics in the JIT area, so having a session or two to talk about those and how to move that forward would be beneficial.
