Not sure I'm getting you… An extension to view old pages? This is the worst idea I've heard in a long time. The web is awesome partly because it's backwards compatible.

I'm not saying I want that, I'm saying it'd be super simple to do if things came to that.

My primary point is that presentational markup is not required to get value from all but the most meta of old pages.
