I wouldn't assume that, mostly because some of these strat players are insistent that the block heel contributes to tone. This is why most custom shop Fenders and Charvels are still being made with the block. If Mayer is one of those dudes, then its going to have a block heel. It's silly what some people think contributes to a guitars sound. Same thing with pressed saddles. That is another thing I consider BS as well. Yeah, good reason to irritate and cut the crap out of your hand. If I bought this, I'd definitely tape my hand where it hits the bridge.
The saddle height screws can be fixed with good design. For example, Callaham saddles are bent and threaded in a way that allows use of shorter screws that won't protrude.
