Hi

Hope that you have started the new year with lots of new energy.
We (me and Koen) have updated https://github.com/quicwg/base-drafts/wiki/ECN-in-QUIC . The main changes are that a lot of superfluous text is removed, for instance there is now only 1 alternative for the ACK+ECN frame. In addition all the extra text that discussed the timestamps is now gone. The ECN capability check is also clarified. Furthermore it is made possible to set ECT also after the ECN capability check.

There are some questions

  1.  I have added some text that outlines how the overhead can be reduced, this text is somewhat speculative and needs more details to qualify as specification text. Should we have this text in the first draft version or do you prefer that it is removed ?.
  2.  Given that this work is presented at the interim, is it necessary to write up a draft or is it sufficient to present the wiki ?
