I think it would be a significant missed opportunity to not share the 
registration and the definition.  Multiple independent parties invented nearly 
the same thing and Francesca was right to call this out.  The edhoc use case is 
a profile of the general facility.  I believe the plan Francesca outlined to be 
a good one.

I'd be glad to talk with you about any of this in person in just over a week. 
:-)

I completely agree.
The easiest way to not imperil lake-edhoc is to not change its registration 
while it is in the RFC editor queue.

As I mentioned, I'm not sure it should be shared, because the semantics differ.
