Does this mean that the -a option could or should be assumed to
always be on?
This looks to me like netstat(1):
- If you provide an interface and parameters, they get applied.
- If you provide an interface only, its configuration gets
listed.
- If you don't provide any parameter, all the interfaces get
listed.
With the above sysctl(8) patch and an always assumed -a switch
you get something similar
- If you provide one or more variables they get listed / applied
(depending on the '=' operator and the RHS expression).
- If you don't provide a variable, all the settings are listed.
- Optional, and I think it's already and still there: Depending
on whether the variable provided is a leaf you might get the
terminal variable or the subtree.

Would the -a assumption break anything? If it doesn't, I feel it
adds similar comfort like the netstat behaviour does in case of
interactive sessions.
