Thanks. There have been a considerable number of messages on this topic, you have made every one of them seem ill-informed by comparison, including my own.
I can't help but worry that TSV is a leading edge case for a general malaise within our community though, which is that we are reliant on a very few people being supported in committing all their time to the IETF.
