Even without modules (A person wrote a program which undid some of those
problems for us in EPEL), EL8 is not easy to build. Packages and software
themselves have gotten more interdependent and complex. This leads to a
larger and larger chain of 'buildrequires' and 'requires' for each package.
To get some of the XFCE packages into EPEL you need to bring into EPEL all
kinds of quaternary packages so you can build the tertiary packages which
are needed for the secondary packages which allow you to get something like
xfce4-cpufreq-plugin-1.2.1-7.fc33.src.rpm built. Each of those packages
needs a maintainer who wants to deal with them in EPEL which requires them
to run an EL to test.

I tried an experiment during the RHEL-8 beta to see what it would take to
get EPEL-8 1:1 with EPEL-7.. I gave up after adding nearly a thousand
packages to the 'build chain' which were not in EPEL-7 nor even in the
RHEL-8 beta or its 'buildroot'. These were mainly packages that are in
Fedora already and would need to be maintained in EPEL and no one wants to
do that.

This was supposed to be a problem modularity was to fix.. so you need 100
packages not in EPEL for your 1 application set, and you don't  want to
maintain those extra packages? Just put them inside your module build chain
and deliver what you wanted. Of course that is still a monumental task and
most packagers would say 'meh I got better things to do, like do a root
canal without anesthesia.'
