Note: Please be sure you create an issue related to this merge request and the issue is labeled StatusReview, this will initiate a CHT member review of your merge request.

NOTE: the CI failure seems to be related to the lack of a CaC release with the 2204 stig profile. I'd recommend holding the merge until you are sure your pipeline has support for the 2204 label.
