Well, I have had many such discussions with XC/XL folks, and that was my opinion. I have seen almost no public discussion about this because the idea had almost no chance of success. If it was possible, someone would have already suggested it on this list.
Or perhaps people invested in this area had other obligations or lacked motivation and/or time to work to push up for things in core. That's not possible to know, and what is done is done.

OK, I will send you a separate email and you can then supply their email addresses.
FWIW, I would be interested in that as well. I worked in this area of things for a couple of years as well FWIW.

I certainly have heard nothing about it, except third-hand people telling me a meeting is happening. I assumed those meetings where XC/XL-specific.
Yep, that's my understanding as well and AFAIK as I know things have been carried this way until now, aka XC/XL and Postgres core are aimed to live as separate communities.
