Opaque data blobs is what RFC-5277 can carry.  The WG asked to update RFC-5277 using the improved control plane of YANG-Push.  This is what makes up the documents in LC.

The drafts in LC adds RPC / signaling mechanisms.  The opaque data blobs are not in scope.

It would be helpful to get some comments on draft-ietf-netconf-notification-messages.  This draft address improvements to the opaque data blobs.
