I don't have much to add to the discussion of this draft (and the 


related draft-hoffman-tls-master-secret-input-01) that happened on the 


IETF list already.






At a first pass, I'm a fan of at least adding an applicability 


statement; the current draft doesn't say much to implementors about 


why they might or might not want to use this extension.  And, putting 


myself in those shoes, I think I'd find the existence of this draft 


more confusing than helpful.






And I observe quite a bit of opposition to publication of this doc on 


the IETF list.
