Yes and no. IMHO...

* Yes if somebody makes a separate executable whose inputs are through
  stdin, command line args, environment variables, and intermediate
  files, and whose actions consist of doing the right things with
  /sys/fs/cgroup/... or wherever, and which is run ONLY by a process'
  run script, and requires absolutely no change to existing s6 stack

* No if any code within the s6 stack must be changed. So much good
  software has gone bad trying to incorporate features for only the
  purpose of getting new users.
