This is indeed interesting. To be honest, I think we will discover all
kinds of unanticipated behavior with BIND 9 and have to make some
decisions about how closely to follow it. We may even take the
opportunity to document these as an informational RFC....

Like with your merit.edu example, Jelte tells me that a big problem with
Unbound development is that people say "it works with BIND" and expect
all other products to follow, regardless of what standards say.

Fun times!
