Doing a better job of RHEL 8's published graphical installer could be
done, but it would no longer be directly Red Hat based. Frankly, I
gave up on the things for large environments, and published PXE setups
with kickstart files that had *much* finer resolution of deployment,
especially using multiple %post scripts to keep the operations in sane
source control, to set varieties of PXE configs for distinct setups,
and that did basic things like running "yum -y update" or "yum -y
install epel-release && yum -y install [ useful bits ]" as needed.

Since what actually gets installed by the RHEL 7 or RHEL 8 option is
never explicitly listed, it's useful to do a reference audito with
"yum list" right after the system is built, and keep a copy for
reference with the different selected options. This is where
"infrastructure as code" becomes your friend, because you can keep
copies of this stuff in a relevant git repo.
