There are niche operating systems (it was posted on HN but I can't remember the name now) that consider application windows and tabs as being one and equal; you can even have one window that has tabs from different applications.

I mean "tabs" is just one of many forms of hanlding multiple windows. They make a lot of sense for document viewers and alike. My claim is that browsers are so much bloa..^Wbigger that that. There is no reason to limit web apps to that document viewers type of window handling.
