Christian,

Thanks for your response! In-line...

There seems to be plenty of empirical evidence that that's not the case.

Not that they mean to break things, but they do -- e.g., a box that 
rewrites TCP sequence numbers, but fails to rewrite the SACK options. 
And many many others.

Don't we have a standards process for this, as in "Publish a draft that 
formally updates RFC8200, gain consensus, and get it published as RFC"?

Or, where/when did things change to "This wg has decided to violate the 
specs from another wg"?

And, more generally: does anybody do anywork or have a say on the 
architecture of the whole system?

For instance, we have an "Internet Architecture Board". Does the IAB 
have a say one the architecture and principles that we're developing 
specs within?

Thanks,
