The proposal (http://www.belshe.com/test/xmlhttprequest.priorities.html) says it's safe to ignore:

"Browsers are not required to support the priority requested by applications, and may ignore it altogether."

I think it's fine that most WebKit implementations ignore it. Chrome will use it soon.

It's modeled after lineCap and lineJoin in the canvas tag. I think the thinking is that it'd be easier to add to or change the priorities later.
