FWIW, I'm not claiming to represent vendors. However, I do chat with
vendors from different fronts very often, and there is a general
agreement on each of the issues I mentioned (specifications being
outdated, the impossibility to produce a real-world TCP implementation
from the IETF specs, the unnecessarily huge amount of energy that is
spent on non-real issues, etc.).

At this point in time, I just want to get this document published. But
the points I have raised are very general issues that affect not only
this I-D, but many other I-Ds that this WG is working on.

Will do.

I have not problem with that, but... isn't this what the WGLC is for?

This has been discussed in other threads and posts, so... in the hope of
keeping a good signal/noise ratio, I will not respond. :-)
