This standards action follows the IETF LC of  draft-ietf-dnsop-maintain-ds 
which achieved IETF consensus as a standards tack update to RFC 7344. 

RFC7344 specifies how DNS trust can be maintained across key rollovers 
in-band between parent and child.  draft-ietf-dnsop-maintain-ds 
elevates RFC7344 from informational to standards track and adds a standard 
track method for initial trust setup and removal of secure entry point.

The methodology described in RFC 7344 was be widely accepted and deployed;
operational experience supports this reclassification and further extension.
