Yes, I fully agree.
Our prescription is to set the correct squish distance, which should be around 1mm, and do a valve to piston clearance test. If there is any piston/valve touch, or insufficient clearance, we will make relief cuts in the piston crown to suit, so that we can retain proper squish distance, and also have appropriate safe clearance for the valves. We like .060"(1.5mm) for intake valve, and .100"(2.5mm) for exhaust valve clearance from the piston around TDC.
The area of concern for piston /valve touch is around TDC, and up to the point where the piston begins descending down the bore.
