Hi Kai, Thank you so much for giving a nice summary and sharing your personal view on the active drafts. The WG sure has many remaining issues to solve and many drafts to go through. I will try to use some of your comments below in the discussion slot :-). I am sure the WG chairs and other members have many considerations/inputs as well. I understand that you will not attend in person. Are you able to call in during the session, or use jabber to give comments.
Thanks!
