But as you say, bicycle tyres are neither wide enough nor do you travel fast enough to aquaplane, so channels/voids/grooves serve no purpose (on road tyres, off-road knobblies are a separate case).
They do serve a purpose on less than ideas road, gravel etc. and actually reduced the risk of puncture as the channel mean any object get caught will not get embedded further into the tyres.

I've only had a quick look, but I can't find where they say that: link plz.
I'm happy to be corrected, but I cannot understand how less rubber in contact with the road, can increase traction.

Bearing in mind that those two, small contact patches are all that's keeping you and your bike from sliding down the road/under a car/off a cliff, tyres are the last place I'd look to skimp.
