From https://bugzilla.redhat.com/show_bug.cgi?id=2101355:

Currently "yum install @server" will install:

• NetworkManager-team which is deprecated on RHEL
• iwl*-firmware which are unneeded on servers
• bolt which is unlikely to be needed on servers

And perhaps something else not helpful. At least the first two above would seem something that could be removed from the group (and possibly other groups). Thanks.
