Yep. See: 
"Fedora will remain the first upstream of RHEL. It’s where every RHEL
came from, and is where RHEL 9 will come from, too. But after RHEL
branches off, CentOS will be upstream for ongoing work on those RHEL

Right. It's not as far as I know.

I don't think this is intended/possible. 

At some point RHEL9 will branch off Fedora, and at some point after that
I would image there would be a new centos 9 stream that appears (after 9
beta? before? not sure). Centos 8 stream would keep tracking the 8.x
point releases.
