Given the new Change Proposal, we are going to consider the issue still open. Here is the relevant issue status link:
<http://dev.w3.org/html5/status/issue-status.html#ISSUE-134>

The bug has also been re-closed for now:
<http://www.w3.org/Bugs/Public/show_bug.cgi?id=10831>

However, in the future we will treat a closed CfC as a binding Working Group decision with the same weight as a survey decision, and therefore will only allow a standard issue reopen request as the remedy. Meaning, the original resolution will stand until and unless a new decision comes down. See this Decision Policy bug for details:
<http://www.w3.org/Bugs/Public/show_bug.cgi?id=13305>

Informally, I would recommend integrating the new data directly into the Change Proposal as it will likely be found lacking in review down the line otherwise.

Regards,
Macie
