I'm not intimately familiar with W3C processes -- but I must ask -- why do you claim this action is "nothing to worry about"? The latest revision reverts  changes made by the chair decision "applied no later than the end of day on the Thu 12th of May [2011]".
http://lists.w3.org/Archives/Public/public-html/2011May/0138.html

The proposal Richard has been floating recently simply covers TextMetrics and has little-to-nothing to do with the chair decision from May. It was requested that the issue remain separate from the May action by the chairs.

I'm thoroughly confused as to what the subject is, when you are referring to "your proposal". What weight or authority does the decision from May have? The patch was applied by W3C staff as the editor would not apply it himself. The editor recently reverted the change, and neither the chairs nor editor have provided an explanation.

I think we all understand that the existence of an implemented API across two independent implementations is an often used and accepted measure for writing the standard. Many implementers are hesitant to put in such implementations in relation to accessibility until there's some guidance from the w3c. We seem to be in a catch-22 here.

Further, the editor of the HTML specification has repeatedly rejected use cases put forward regarding Canvas accessibility.

I've repeatedly written summaries on this list, and will continue to point to that data. There is a summary in the bug report itself, in fact, that bug report was simply issued based on a lengthy summary of use cases and arguments against those cases.

They've been escalated as far as I'm aware.

The HTML editor continues to assert that interactive Canvas accessibility is not an issue as Canvas should not be used for interactive components, beyond an arbitrary set of button, checkbox and radio. This is reflected on the whatwg specification.

We're in a bit of a bind here.

I'm sure vendors will move forward, regardless, as they have real-world commitments to accessibility. The chairs previously put forward a decision which has now been circumvented by the HTML editor. It seems odd to submit Change Proposals under such circumstances. Why go through the process if it holds no authority?

Cute.

Tell you what, Sam Ruby, I'll keep an eye on this thread while Richard is on vacation.

If you feel it worth your time to respond, here I'll be.

Meanwhile, I will comply with Ian Hickson's request, posting links to the various use cases discussed on this list over the past two years.
