The procfs hidepid option still defaults to 0 (visible), but systemd will set it to 2 (invisible).

  On Linux, the permissions on /proc/$PID/environ are the same permissions you'd need to read the memory of the process, so just being able to list that dirent doesn't give you anything. Though I do think that command lines being visible to other users is a design flaw.
