[Podman] RHEL 8.4 - No private unshared labels

Hi, I have a RHEL 8.4 box , totally updated, using the "container-tools" module (with the default rolling stream) and noticed that there's no distinction between creating a volume with "z" or "Z". If I use "Z" I never get a "private unshared label" in the corresponding folder (no MLS fields). Is this really not available in RHEL 8.4 or am I missing something? Thanks, Jorge
