[CentOS] epoch rpm el8 obsolete?

I am building a new workstation based on EL8 now. As someone else here mentioned, the raw EL8 distribution 
is unusable as a workstation. Therefore I am building lot of additional packages. Today I came across a problem 
with a custom package with an Epoch version, that kills the yum/dnf update process (it tries to find a "best" 
package etc.). My actually question; is the RPM Epoch stanza obsolete now (for EL8)? I remember that they also 
started to delete Groups categories ...
