Would it be possible to make it a SIG requirement to reach out to
relevant RHEL Product Owners before the scope is extended to additional components?
The RHEL team(s) will be collaborating and participating in the SIG. You shouldn't need to reach out to us, as we'll watch mailing lists and participate in Matrix where applicable. We're having various internal kickoff meetings with our kernel teams, and highlighting the importance of the community and CentOS for enablement. You'll see Amnon Ilan and myself actively participating in the SIG.
