Thanks Mark, but my question wasn't about how to get a particular proposal adopted.  I'm trying to find clarity on how we would distinguish these two working groups.

The purpose of these two examples (one current proposal, one historical) is just to give us something concrete to deliberate.  Are these examples of HTTP work, or HTTP API work?

Distinguishing these groups seems important because they are so similar.  If we have trouble identifying which group should take which work right now, when nothing is at stake, I could imagine difficulties at scale.  I'd love to find some clear criteria.

So far, the reaction has been of interest, but I'm not sure we're quite to the point where we'll adopt it; personally I'm still looking for more people to say 'yes, I want to implement that' and/or 'yes, I have a use case for that.' That may still happen, in time.
