Nice.

Well, can't we support both? I mean, even if you configure 2 nodes you'd
need 4 values, right? So, there are no cases where you only specify 2
values.

Well, let's make it like this: if you provide 2 values, it acts as you
say above; otherwise you have to specify all of them. If you should have
specified 4 (or 16) values, and you specify, say, 3 (or, say, 10) all
the unspecified ones will have the same default value (e.g., 10). How do
you like this?
