Hi Eric,

Thanks for this review. A reply can be found below. I apologize for the long delay over the holiday season.

The authors have published a version -08 that hopefully addresses your comments. The full diff for -08 is available at:  https://www.ietf.org/rfcdiff?url2=draft-ietf-tcpm-yang-tcp-08

Agreed. We have reworded this to "configured and managed".

There has been quite some discussion in TCPM about the relevance of YANG for TCP stacks, and this paragraph tried to capture that. A significant number of TCP implementers in TCPM has never dealt with YANG models, which is at the time of writing mostly used in routers and other network equipment, but not in client and server operating systems. 

Yet, your question seems reasonably. We have this removed this paragraph -08. If somebody insists in having this text back as additional background, please speak up!

Rephrased to "does not deprecate"

Yep. Sorry for that.

This should be fixed in -08.

Thanks!
