CentOS - Dec 2020 - dnf script to cherry pick updates and maintain RHEL compatibility

Here's an idea, though I don't know if it would be practical.

I assume that at some point everything that goes into RHEL and its
"official" updates travels through the Stream ecosystem beforehand.

So what about the idea of maintaining (somewhere) a list of official updates to
RHEL as they are released, and then have some kind of a dnf enhancement or
script that reads that list and updates a local Centos installation using only
the rpms on the list and ignoring everything else.  Stuff that's released to
Stream would be downloaded and installed at the point where it has been released
for RHEL and not before.

That would (I think) keep your Centos installation in sync with RHEL.

That (if it worked) would only work up until the stream reaches EOL at the end
of 'Full Support mode '- which for EL 8 is 31st May 2024 (not as we were
expecting, sometime in 2029)

Or even better, as Redhat appear to be taking full control of 'CentOS',
why don't they just make RHEL available to all for 'free', and you
just pay for support if you need it - i.e. a bit like it is now, RHEL if you
pay, CentOS if you don't - I'm sure that would make everyone happy :-)

IMO - this does not work because no intermediate update will survive in 
the stream repos. If something moves on then the state that reflects the 
current RHEL release can't be reached anymore. Or we have a mirror 
service that save all packages/stream releases ...
