Security issues are high priority to fix, otherwise it takes (usually)
complaints from paying customers and/or effective lobbying from the
package's maintainer. They have finite bandwidth for package updates,
and they also take seriously the idea that a RHEL release series is
supposed to be a stable platform. When I was there I was usually able
to get them to update to new PG minor releases only when said releases
involved security fixes, otherwise the can got kicked down the road...

If you want a fix in Red Hat's version of 8.4, you need to be talking to
them *now*, not "at some point". The community lost any input into that
when we stopped updating 8.4.

Yeah. Also, Red Hat is shipping a newer version (I think 9.2.something)
as part of their "software collections" packaging initiative. I do not
know whether that's included in a standard RHEL subscription or costs
extra.
