[Roni Even] The process of having a DT and blocking discussion during the time for the 4 month between the meeting slowed the progress. This WG trues to work in a fast pace and I think that in Singapore and on the mailing list we saw strong support from the parties who will use the spin bit to move it fast. Waiting for London will further delay.
I was planning to provide replacement text for 609 this week or no later than next week, defining the spin bit based on the discussions we had in Singapore and on the list for a new PR for the QUIC transport document.
We can have in parallel a non WG document on RTT measurements using the spin bit even though it place may be in the QUIC manageability document.
