so, iiuc, the difference is that "type forward" sends queries with RD bit
set, while "type static-stub" sends them with RD cleared... and
the "forward first" option appears to be applicable only in forward zones.

did I get it right?

I use forward zones for blacklists - while I mirror some locally, but when my
mirror fails, the usual resolution takes place.

If I'm right, this is not possible with "type static-stub" zones.

I wonder, what are expected usages for this kinds of zones?
Maybe blacklists, if we have local mirrors and traffic so high that we'd get
blocked imediately?
