To be fair, I actually like ideas like this. Anything that increases the likelyhood of engines breaking is a good thing. F1 engines are now over engineered for the task, it's why you just don't see many engine blowups even with extended usage.
To all those saying that piston to bore is transition/light intereference fit until it's up to temperature, so you can't do a cold start. The engineering challenge then beomces reducing wear at cold running whilst not losing performance.
Also technology transfer is not just about gadgets. Heat treatments, coatings, manufacturing and assembly methods aren't as 'cool' but is very transferrable knowledge.
Eg, a bore coating that reduces running friciton by 10% at the top end, is never going to get the same press as a bolt on gizmo that gives a 1% performance advantage. Or a little widget that fiddles with the air a bit.
