Tabs are for workflow; they're a completely different modality for working with a browser, and it's not about MRU.

Many of my tabs are open for months at a time, often whole trees of dormant tasks, collapsed. As to screen real estate, I haven't maximized my browser window since about 2005, when I moved to a wide screen. Almost all pages don't render well to a wide screen format since it's hostile to reading, and for those that do render well, typically videos and presentations, full screen is better.
