The point is that it is there and it is useful - I like being able to load external URIs into the browser without stealing focus from my current tab. What I don't like is that the window itself is raised every time; Firefox never used to do this, and many people attributed the loss of this behaviour to changes to TBP.

That's basically what the point of this bug is. How hard would it be to add the necessary core APIs to allow focus to be suppressed when tabbrowser creates new tabs?
