Kindly tell me why. I looked through both drafts thoroughly 
and see few benefit to merge them. 
 
I point out the lengthy discusson is entirely about Sathya's 
draft & few word is mentioned on CPL draft. I wonder how 
you come to the merging recommendation from that.

I wish we discuss on whether we do this or not first, before 
deciding who will do this.

I take notice of the word 'unnecessarily'.

I agree. BCP work is to present a way (or ways) to perform DNA 
without standard change. I understand that BCP & Solution aim 
the same thing and 'whether standard change is allowed or not' 
is the main, or maybe only, difference between them.

The reason I raised the issues about BCP draft is NOT that 
it present incomplete solutions BUT that it contains materials 
that are not part of BCP solutions

For example, the draft talks about how a host performs DAD 
after DNA completion. Though I think it would be helpful, 
I don't think that's part of DNA and wish BCP draft focus more
on how to perform DNA without standard change. 

Actually those materials, such as DNA & DAD or DNA or 
bi-directional reachability, concern both BCP & Solution works, 
so I think, for organizational point of view, it would be better 
to present them in a separate draft, not inside BCP. 

Do you still think it's wise for BCP draft to contain those 
materials, such as DNA & DAD?
