I expect this to still work, but I think GP and I want the "subscribe to this page" button to still work, and send the rss link to the user's third party reader. It's nice to have rss links open in the right app, but there are a ton of sites that don't have an obvious rss link on the page, but it's embedded in the html because of the spec.
