[whatwg] A plea to Hixie to adopt <main>

I generally markup pages using ARIA roles:
and variations thereafter—
If there were to be a <main> attribute (with an implicit ARIA role to match), where would it end? <contentinfo> <banner> ?
What is to be gained by adding an element, rather than using ARIA roles? Isn't that what ARIA is designed for?

However, I think using <main> as a way to opt out of the heuristic works better than using <aside> to opt out of the heuristic. For instance, it seems reasonable to use <aside> for a pull-quote as part of the main content, and you don't want that to be excluded, but the Scooby-Doo algorithm does that.
