While I most certainly agree with this, I'd back up one more step and ask whether there is a real problem to be solved or if this is about a perceived problem?

I.e. unless I misread the original message it was only about optimizing the order of the name servers in the response packet, not about changing the actual response to the query. 

And as long as we're only talking about the order of the NS records it really is a non-issue, because that will still be subject to the resolver strategy in deciding which one is "best" for them.
