Assuming Centos stream is still having point releases, how different is tracking the previous point release of repos from using centos currently? e.g. if this is what the tick-tock looks like: day 1: Centos stream 8.3 is being updated and maintained day 2: RHEL 8.3 is released based on stream 8.3. day 3: Centos Stream is now 8.4 After day 3 can you still just track 8.3? Is the issue that centos package repos won’t get updates (particularly security updates) at that point, while RHEL does?

CentOS has never released backported updates to previous minor releases. You've always had to stay on the latest minor release, so it's not like there's any real change here.

  Right, but the difference today is that Centos is always behind RHEL updates though, yeah? In the future, Centos Stream is always ahead of RHEL point releases, and on day 2 they are close to equivalent, and on day 3/4, centos is goes back to being ahead (at 8.4 and getting security updates), where rhel is at 8.3 and getting security updates. Assuming that, on the day of a RHEL point release, the two distros are roughly equivalent in packages, with the caveat that the Centos package repos at that point move to the next release (8.4), so you don't get any updates ( presumably mostly security related) in the 8.3 repos... at that point - with those assumptions, if you were on the previous Centos (8.2) - would waiting for the RHEL release to upgrade to the next, now unsupported Centos point release (8.3) be close to roughly equivalent with what the situation is today in terms of compatibility/stability? (I'm not sure what the answer there is) Or - could just track behind a minor release to approximate the situation today with the caveat that you're not going to get all the updates? Does Rocky linux end up just being the previous centos stream version with updates to the package repos?

    With the caveat that security backports go into RHEL first and then into Stream.

Stream will not have point releases.
