Ok bad choice of words.

What I meant to say was that the output of a design team doesn't
automatically get adopted by a WG.

_If_ they choose to write an I-D (say an I-D summarizing some
proposed changes) as input to the WG then that I-D doesn't
automatically get adopted.

I'm sorry if that was confusing.

Fair points but they should be answered by Kelly and Phil and others
who raised issues at the mic in Vancouver.

This issue is an example of something that actually _may_ require a bit

as is this...

This list is a pretty good summary of what has been raised so far.
