While looking at the Bodhi code trying to figure out how to fix a really old and annoying bug for EPEL7, I've realized that zchunk metadata is not produced for EPEL8/9 because of an old assumption about EPEL using yum and not supporting zchunk (see these lines).
Do we want to change this behavior? We may now check if a release has dnf set as package manager and use that to determine if enabling zchunk or not.
dnf
BTW, it would be nice if anyone can have a look to the reported EPEL7 bug, I'm not sure if it's Bodhi or yum to be faulty (see my last comment there).
Does RHEL with dnf enable support for zchunk, I'm not sure here, there was discussing explicitly removing the deps/options, and if that's the case zchunk wouldn't work.

So RHEL does not ship with zchunck functionality as can be seen here in c9s libdnf: https://gitlab.com/redhat/centos-stream/rpms/libdnf/-/blob/762f631e36d1e42c63a794882269d26c156b68c1/libdnf.spec#L45
So I don't believe we can enable zchunk support in EPEL
Thanks, no need to adjust Bodhi code then.
