When Apple says "you might damage your display because the clearance between the display and keyboard is designed to very tight tolerances", do they mean?
- the display itself could have scratches?
- the display connector at the hinge has a chance of weakening?
- others?

Edit: Also, from my limited research, the repair cost w/out AppleCare+ (or regular AppleCare if they don't count it as accidental damage) is around $1,000.
On my MBA there's a small metal lip around the lid and the LCD is recessed into that. Something thicker than the lip sitting on the glass would negate the relief the lip provides.
When the laptop is closed, the webcam lands around the bottom of the trackpad. There's a small gap between the screen and the lower lid, and the trackpad is recessed slightly, but not by much, and it doesn't have any "give". A bulky webcam cover will strike the trackpad and may shatter the glass of the display and/or the trackpad, especially if the laptop is closed quickly.
