It's not bad, but I think it's unfortunate that nobody is working on it. The sooner that HTML5 features are implemented, the better. I thought that posting it here would get some eyeballs on it!
I posted links to the mailing lists in my other comment; if you haven't already, posting a thread to them asking about the priority of the bug would be a good way of getting the attention of a bunch of devs and planning people at once.
