This issue also exists in RHEL 9 and Fedora 37. The lack of this feature currently prevents me from using the system-wide crypto-policies. However, I think that a system-wide crypto-policy is great and strongly needed and therefore would be very happy, if this could get resolved. How could one potentially help with that?

Converting to Fedora bug, because I do want to address this request one day, but I don't have a clear way forward, and whatever the solution will be, it's unlikely to be ported to even RHEL-9 at this point, let alone 8. For them, opting out of crypto-policies is the supported solution.
