Yeah thats what I thought about it to but the more I thought about it, if it just displayed the values changing instead of the description when =N is supplied I think that would be acceptable to. 0 -> 1 in this case. Or possibly sys.oid: 0 -> 1 # <Description> since sysctl.conf(5) also takes comments like that.
Not really thats something at the top of the list for fixes though. Low fruit. Food for thought.
