Cullen,

thanks for the comment.

"make before break" is indeed one of the objective of this, citing the first
requirement:
"The solution should take care of handover as fast as possible."
We can change the wording to take into explicit account your comment.

Please also note that in the draft we reference:

And also please note that Stefano recently released software for 
the handover solution:
