I don't remember any consensus call, hum, or anything else
being taken on protocol selection. Rather, I remember there being
presentations with questions and minimal discussion.

All this is great stuff, but it all happened after the BOF, so
you can't reasonably claim that it represents BOF consensus.
And since BOFs are our primary mechanism for open, cross area
assessment for WG formation, I don't think it's accurate to suggest
that this is anywhere as near as open as actually having the
discussion in the BOF and gettting consensus, nor is it a substitute
for that.

Perhaps that's true, but I don't see that that's an argument
against actually running an open process rather than declaring
a winner in advance and asking the IETF to ratify it.
