Yes, we could have better defaults, but this problem is fairly simple
to fix via appropriate configuration (unlike the RP-mapping issue
being discussed). So don't agree on the importance ranking :).

That said, I am open to putting in a better default in the spec. Will
include this in the longish todolist we have for this document...
