It actually feels more like a pseudo-class to me, though I can understand those who disagree.

We could have both, actually. One could be syntactic sugar for the other, allowing more freedom for where authors want to write their rules (do I put the 'article:page(right)’ rule right after my 'article' rule, or do I put all the '@page:right' rules together in a block?).
