I don't think so. It seems to me that 1034/5 is not prescriptive in the strategy
a resolver must or should use. I think resolvers wishing to use strategies involving
explicit NS requests (for example for privacy reasons, or to minimise the number
of parallel queries at start-up ) are free to do that.

Resolvers should not assume that the root is delegation only though.
