I'm not sure how this makes sense.  The limits are enforced and
collected per user or along the process hierarchy which can be very
different from cgroup organization.  What does collecting high
watermarks from orthogonal structure, sometimes even combining
per-user numbers from different users, even mean?  These are numbers
without clear semantics.

Thanks.
