Just a quick reminder about SIG content also going away end of this 
month, *except* for SIGs who have opted-in to start building against 
RHEL8 (and so far we only got kmods/ceph/nfs-ganesha so all the rest 
will disappear - see 

Worth knowing that the CentOS Infra tags and configmanagement ones will 
stay in place, as used by the centos infra (and yes, building against 
rhel8 but still applying on 8-stream just works fine, as we use that for 
months and 8-stream is just 8)
