What's the point?
I mean, CentOS stream will be freely available (probably) and at least with stream, you don't need to wait for the security-updates.
I think a lot of people didn't realize just how far CentOS had been lagging behind RHEL recently. Especially in the early 8.0 days, with months without an update.
There's no such thing as a free lunch - people seem to forget that all too often.
While you can get almost all Linux Open Source software on Debian and Ubuntu, most of the enterprise-software that makes RHEL actually an Enterprise OS is either simply not available there or unsupported.
It all boils down to what you want to do with the installation. The typical Wordpress blog does not really need to run on a 1000 $ / license / year server.
But a service that a couple of hundred or thousand hosts rely on (like IPA or Satellite Server or 389 directory server) is something different.
