Just re-measured with a USB flash drive and an actual MacBook Air M1 (which I'm actually typing this comment on), and it's not. Do you want a photograph with a caliper?

> But whatever, whether it fits or not with the current molding, the laptop does not need to be thicker to fit those ports. It just needs to change the curve near the back. Look how thick the middle is between the ports it has. That's way more than enough. Thickness including screen peaks at 16mm.

Actually, you can see in [0], there's no space to fit a full depth, full height USB-A port inside there. You need to make the machine definitely thicker to accommodate that ports, given all the shielding a USB-A port around it [1]. This is a listing for a straight port. You'll probably need a 90 degree version in a MacBook Pro, unless apple does something ingenious.
