As far as I can tell, the proposed markup works in legacy browsers, too.
I like it, except adding square brackets with CSS. Uses that are the most likely not to support CSS are exactly the uses where the brackets are most needed.
Good. I think it's ok to keep the brackets in the HTML code -- it's a common style and we can affort the extra two characters. This is also what the study proposes.
