I've had multiple times where I wanted to do other things while CS2D launches and it disrupted my work.
EDIT:
Also if you idle in the main menu for too long, you'd need to refresh your USGN by either restarting the game or going in and out of the editor (or using the hard to reach USGN refresh button near your username).
Otherwise you'd be stuck in the verification phase, forever (not good).
