Hi Ashok, I wasn't particularly arguing for 1 as much as I was trying to answer Henry's questions regarding John's proposal. I'm not sure what makes you think that "the WG was moving towards 3]. We only hear about a handful of people on the mailing list while the WG counts many more people. This being said, I think your summary is a good highlevel descriptions of various options we can have a strawpoll on. We will do just that on Monday! In general, I think we've had enough of general discussions and I plan to have a lot more strawpolls moving forward so that we can narrow down the discussions.
