I believe that the short answer is that *you* have done everything that
was available to stop this document (and others) from moving forward.
Requesting text to be added, then requesting the very same text to be
taken out of the I-D. And at some point, we ended up changing the track,
changing text, and changing whatever was out there just with the hope
that you'd be happy, we'd stop wasting energy, and the document would be
eventually published.

It is interesting to note that one of the issues with with you have
trashed this I-D is that it used vocabulary that could be taken as the
draft "recommending" the described counter-measures. Yet, as the editor
of the last version of the (close to infamous) TCP A-O effort, you have
crafted this text:

"  There are other mechanisms proposed to reduce the impact
   of ICMP attacks by further validating ICMP contents and changing the
   effect of some messages based on TCP state"

Note the use of the term "proposed". (that's specifically what I'm
referring to).

I believe this is the height of irony.

Thanks,
