I don't even understand your argument. For example, if in my web browser I open multiple news stories from from the same news page, I still want the tabs histories to be separated, because each story is independent of others. It's almost like every time I follow a link on a new tab I'm creating a new little project (learning something new in this case). Should the tabs histories be intertwined just because they all come from the same main webpage?
I've read the entire thread multiple times and I don't think I bring any new arguments to the table. Everything has already been said. I mostly just wanted to make another +1 for this feature request.
TLDR: I am not trying to say my logic is better than your logic. I'm merely asking you to reconsider to implement this feature as optional *even though* you don't want to, simply because many of us users do want it
