I would rather we abandon this draft.  I don't think the benefit is
worth the cost.

It is not my impression that the load on the roots from special-use
leakage is a significant fraction of the overall flood of garbage they
get.  Whether or not it is, we have at least three things going on
that would decrease all root garbage queries, not just leakage:

RFC 7706 (local root mirror)
	
draft-ietf-dnsop-nsec-aggressiveuse-04 (Aggressive use of NSEC/NSEC3)
	
draft-ietf-dnsop-nxdomain-cut-05 (NXDOMAIN really means there is nothing underneath)

R's,
John
