I don't have a clue why anyone would want to hide processes, and make
their own lives more difficult.
The check with hidepid is can you ptrace the process. I expect there
is something with those sgid processes that keeps you from ptracing
them.
Of course if you don't like the silly behavior you can always disable
it.
