Well, what are your options? Either move away the heat, which needs things like heatpipes and fans and stuff that dissipates... or create less heat. So if you've got no more place for bigger fans, more heatpipes, more surface area to dissipate heat, you can only start to create less heat by throttling your chips. I think if MBPs were 5 mm thicker, you would have no heat problems at all because you could just build them different.
