Noting that this is from today's Contributor Meeting, quoted from me, which itself was a follow-up from the SIG Security meeting last week.

To close this out:

1. Enable draft GHSAs on the repo, use the same template as CD
   • this requires a repo admin (I do not have permissions to do this, which is why I brought it up)
2. Add a link to create draft GHSAs to the SECURITY.md, same as the CD link above
   • I can do this. EDIT: Completed in docs(security): add Draft GHSA option #12747
3. Add any folks who need access to relevant GHSAs
   • this could be manual per GHSA if desired; CD has given permissions to security folks like Jann and Crenshaw (who are also Approvers)

Thanks Terry, can you also review the security docs changes in #12747 now that it is enabled?
