(Get the code!)
So yes, that is what matters. When a system is booted with systemd 248.3-1ubuntu3, it sets up the cgroups in "hybrid" mode. systemd 248.3-1ubuntu5 defaults to "unified" mode but simply upgrading the package does not redo this setup -- the system remains in hybrid mode. The test cases that are failing on the autopkgtest runners only run if the system is is in unified mode, so the only case where they run is if systemd was installed before the reboot.
OK, so that's settled and I think we can conclude that this is not a regression. So the next question is why do they fail? Well I assume they are not compatible in some way with the focal GA kernel but I haven't proven this yet...
