If this functionality is really necessary, it should ideally work
without having a service running.

Another, easier way out would be to allow /proc/<PID>/stat (and perhaps
others) to succeed even if the process info can't be grabbed due to
permissions.  It wouldn't show really useful info, but procps or top
would at least show the process.
