Aha! I am glad we agree on the lack of consensus in the  WG! I feel that we

Now this bit here is somewhat vexing. Of course I am sure it is entirely
unintentional so let me just correct this:  "Before the meeting, Emil
decided he did not support it" is quite an, obviously accidental but still,
misrepresentation of reality!

You had discussions with people. I was not an active part of them. You put
my name on a slide of "supporters" and you were about to present to that to
the WG. I saw that and asked you to remove my name. Please do not imply
sudden whimsical changes of positions.

Next time my support is important to you, please simply reach out and I'd
be happy to hear you out.

Ah! That "splicing attack"! You often refer to it and have yet to explain
it ... I am confident that you only mean well of course, and promise that,
as soon as you provide details, we will come back with explanations and
security considerations on how to protect against the specific vectors that
concern you.

My very best regards!
Emil
