The W3C process talks in terms of strong and weak, and in terms of 
objections.  Weak is meant to be taken as the opposite of strong, and 
argument for is meant to be taken as the opposite of objection against.

The existence of these guidelines (standards, laws, etc). that you and 
others cited is a valid argument.  To my knowledge, no one is contesting 
that these guidelines exist.  Some have argued that these have had 
little impact.  None of the proposals or objections clearly established 
that these guidelines had an impact.

Just so that it is absolutely clear: there is no assertion made that the 
guidelines did not have an impact.  The only assertion that is being 
made is that there was an issue, we called for proposals and received 
three, there was an extensive period of discussion, and a call for 
objections.  During the course of the above, it was brought to light 
that there are relevant guidelines, standards, laws, etc.; a question 
was raised as to whether such guidelines had an impact; and no clear and 
compelling response was produced during the course of the discuss

To clarify, and from the response:

"In extreme cases, as when a Chair writes a Change Proposal or takes a 
strong position on an issue in the course of Chair-led discussion, it is 
likely that particular Chair will refrain from authoring the written 
decision, should one be necessary. We will discuss amongst ourselves and 
confer with members of the W3C Team on this as necessary. However, we do 
not think it is appropriate to formalize this in a written policy."

So we can, and will recuse ourselves as necessary.  In this specific 
case, while Maciej did provide feedback (but not due to the 2007 IRC log 
you mentioned, but because he actually participated by producing one of 
the proposals, one that the TF supported).  I took the initial lead in 
evaluating this issue.  Maciej's feedback improved the quality of the 
response, but did not materially change the decision.

> Another bug on the policy regarding consistency was marked WONTFIX.

It is not clear how that is relevant here, but again:

"The chairs discussed this issue. We believe that it is not the role of 
the chairs to enforce consistency as the highest value. Rather, it is 
our role to evaluate arguments made by members of the Working Group to 
determine which proposal draws the weakest objections. Thus, if 
particular Working Group members feel that consistency is important and 
believe that a given proposal would violate it, they should cite the 
consistency problem and explain their reasoning, either in another 
Change Proposal or in a straw poll objection."

Again: consistency is clearly a good thing.  But the responsibility to 
produce a consistent document is on the members of the working group.

Correct.

Countermands is a strong word.  Prefers... not so strong.

In any case, from the task force description:

http://www.w3.org/WAI/PF/html-task-force

"The Task Force does not, however, represent consensus of either of 
those Working Groups. All output of the Task Force should be considered 
as proposals, subject to vetting and modification by the WG receiving 
the proposal."

In the short term, a better use of those energies would be towards 
identifying new information (I hear that there is some from Oracle?) or 
on a Formal Objection.

If there is to be a Formal Objection, I am quite prepared to actively 
participate in the process.  My interest in this matter is not in any 
particular outcome.  My interest is in getting this matter behind us.

In the long term, a better use of those energies would be directed 
towards producing more complete proposals.  Note that the following 
proposal makes no mention of standards, guidelines, etc:
