The IETF describes what consenting protocol participants can do.  So, I'm fairly sure that legal authority has no bearing on this.  However, your point remains a good one.

There are relatively few places where you will find that blocking a per-destination basis doesn't happen at all.  No two networks are the same, and many apply policies that affect how your packets are passed.

Maybe it's a shortcoming in the draft, but recognizing that the intent is to provide an indication of whether access meets common expectations for network access should help.

Personally, I'm comfortable with what is there as a set of requirements.  They aren't that negatively phrased, just narrowly scoped.  I think that a more narrowly targeted version of your ICMP draft would have met these requirements, as would several of the other things we've considered.  I might concede - as some have argued - that the resulting value is so greatly diminished as to not make it worthwhile, but that's the essence of the debate.
