Well, what I am trying to say is that if you do it properly then you will not have to consider that, since it will already work. If they user wants to open a new tab, they can middle click (or whatever other method is correct for doing so on their browser, which might not be middle click); if not, they can left click (or tab to it and push enter, or whatever). For state and that stuff is a valid point, but if the browser history and the URLs in the browser history should generally be able to store whatever such things are valid, I think. It isn't browser tabs that are confusing, but rather when you try to override the existing user interface with your own, that makes it confusing and difficult to work with.
