I have cleaned up the epel-next (both 8 and 9) repo's.
If a package was newer in regular epel than in epel-next, the epel-next
package was untagged from epel{8,9}-next.
If a package was the same version-release in both epel and epel-next, I
made sure the epel version was installable on CentOS Stream {8,9}, I also
checked that the epel-next branches were the same as the epel branch, I
also checked to see your building style. If everything pointed to "remove
it from epel-next", I untagged the epel-next package from epel{8,9}-next.
If the epel-next package was newer than what's in epel, I left them alone.
The vast majority of the cleanup happened yesterday, so you should be able
to see a smaller epel-next repo now.
If I untagged a package that you feel should be in epel-next, let me know
in the next week or two and I can tag them back.
If I missed your package and you want me to untag it, also let me know.
