Des\ar Lars,

thanks for your input, I will focus on one single point below.

That makes it quite unappealing to join the discussion for someone who isn't part of those camps. I agree that more of that kind of "discussion" is not going to be helpful. I think the two camps need to realize that they need to convince the *rest of the WG* of their respective views, not each other.

So personally I am at a loss what to think about the L4S RFC-ing process in the WG. Since years there is real testing data showing L4S failing to achieve its promises and goals and yet most of the WG members seem seems to ignore this fact during the meetings. Meetings in which mostly political arguments for RFC-ing the L4S drafts are brought forward like, "I share L4S's goals and hence I endorse its implementation and design" (I am confident not all holding that position have scrutinized the drafts or found time to thoroughly look at the data), or "it took so long already, let's get Brexit^W L4S done" (which is as non-technical as it can get, and not really appropriate for a proposal with demonstrated side-effects on the existing internet traffic). None of these repeated calls to a LC make any dent into the problem that the data shows L4S is not there yet.

	I apologize for not referencing old e-mail threads, but I do try to take care to always include links to data slides and I cite (and link) relevant text from existing RFCs and the L4S drafts. I try to put together the L4S promises (draft text) with data showing where promise and reality seem to diverge. I also try to highlight where I believe the text to be either confusing or outright wrong. What else can I do to engage others (like the impressive number of folks showing interest in progressing L3S in the April interim meeting) into a round of closer scrutiny?


Best Regards
	Sebastian
