Rule 1 for complex and divergent mail threads is to change the Subject header when the subject changes. If you don't do that, your mail is rather likely to get junked. I think that IETF last call threads should stay on the main IETF discussion list. That is exactly the right place for them. It's rather trivial to filter them into a dedicated folder; I have one called 'lastcallsin', that also picks up most WG Last Call threads, although those have less standardised subject headers.
