This is intentional. See systemd's NEWS file:

systemd (247.2-2) unstable; urgency=medium

   systemd now defaults to the "unified" cgroup hierarchy (i.e. cgroupv2).
   This change reflects the fact that cgroupsv2 support has matured
   substantially in both systemd and in the kernel.
   All major container tools nowadays should support cgroupv2.
   If you run into problems with cgroupv2, you can switch back to the 
previous,
   hybrid setup by adding "systemd.unified_cgroup_hierarchy=false" to the
   kernel command line.
   You can read more about the benefits of cgroupv2 at
   https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html
