Sure. The problem is that koji currently uses the builder package
managers (dnf, or yum until it no longer exists) to populate the mock
chroot and install buildrequires. This means after yum goes away, epel
chroots would use dnf instead of yum to do this. This may "work", but if
it did it could well produce different results than yum did.
mock has a bootstrap feature where you can tell it, hey, install rhel7
yum and use that to populate things and install build requires, if we
have support for that nothing could change for epel6/7.

as Dennis noted EPEL6 goes EOL on 2020-11-30, but epel7 longer of course.
We already have a tweak to tell koji which package_manager to use:
mock.new_chroot : 0
mock.package_manager : 'dnf'
Perhaps we could extend that to add a 'mock.bootstrap: 1' to have it to
use bootstrap support? Or, frankly bootstrap support makes sense to me
for everything, so it could just be the full default.

Alternate solution: use centos7 builders for epel builds.
In fact if we have this feature we could in theory go back to our
builders being rhel instead of Fedora.
But yes, we could move our epel builders to just be rhel7/centos7, but
it means we have some builders that are just almost always idle. In fact
we are going to have to do this anyhow, due to ppc64. ;(
So, while I think this is a good thing and I think koji should implement
it, it's not the end of the world for us if it's not in place by f31.
