And yet, there is a complication, since the keyboard and mouse
interfaces are both present on the same device. I just ran a small
test, on an MBA3,1. While it is true that the trackpad generates
wakeup events on touch, it enters a loop of suspend/resume, presumably
due to the keyboard. Moreover, the trackpad emits some strange packets
which leave a (large) message trail.

I've seen the occasional error message on my 3,1, but I haven't seen any 
looping suspend/resume.

You need to sprinkle some outputs in the actual autosuspend machinery to see it.
