(Of course, we should be asking RH... but nevertheless)
EPEL 8 has several issues regarding packages without corresponding -devel. E.g., libXvMC, libbluray. I see that this causes grief for EPEL 8 and collateral damage to RPMFusion.
Did RH disclose the reason for this? Was there any discussion on where CentOS will put them, like in Extras perhaps?
(I was rolling out some testing VMs in RHEL8 and OL8, and noticed the new but "unsupported" CodeReady repos with -devel packages; yet not all -devels are them.)
