My apologies for not noticing this would need to be done earlier.
The group that was once referenced with #security is now acl*security, and Security is now a group that will be open to all parties once we are ready.
The members of acl*security have also been moved to subprojects with meaningful names.
I know there is logic somewhere that needs to be updated, but I'm not sure where. These changes are in relation to T240490: Revamping Security-Team Work Intake and Flows and have been made in coordination with releng already.
