I also don't really see the point.

I mean you can only streamline it so much. You are still going to need to choose your account then log into your account then the whole don't forget your friends and family message hit play (because I really doubt they would get rid of that) to go to the game lobby for character options (create/delete/play) at a minimum. All you really save off of it now is the click to go to the log in button then hitting log in. In light of the rest of the time spent logging in and out I don't see how shaving off that extra 5 seconds or so and 2 clicks will make the difference between your decision to stay logged in or log out.
