Copr just uses `mock-core-configs` package, and the `epel-*.cfg` files
there.

I believe that anyone who will need to do local builds (including Fedora
Copr) will be able to get the appropriate subscription [1], and so we'll
be able to change the epel-8 config from centos+epel to rhel+epel in
mock-core-configs.  Btw. there already are some `rhelepel-*` configs
(feel free to try them, as that's what will be in epel-*, see also [2]).

I also believe that we'll be able to have some subscription for
Fedora Copr builders that will allow us to continue using
mock-core-configs in default variant.

Cross-arch builds (--forcearch) will stop working till bz#1912847 is fixed, and
this would affect Copr.

EPEL content is built in Koji _against_ RHEL+EPEL repos.

I thought that this is normal situation (8.4 release is fresh), and that
CentOS 8 is supported till the end of this year - so please correct me if
I'm wrong but CentOS 8 should still get the 8.4 update?

You both are correct.
CentOS Linux 8, will get the 8.4 update.

This gap happens every six months.  RHEL release happens, and then it takes some time before the CentOS Linux release happens.
It's going to continue to happen with Alma and/or Rocky.

My suggestion is the same as Pavel's.
Have COPR get setup with a RHEL free subscription.  They have something specifically for things like COPR.

But, this is something to bring up with the COPR community, not the EPEL community.  We don't control their machines, setup, or policies.
