A couple things about what you said. New brake pad technology has pretty much reduced braking gas to a nominal amount.
Andy, if you re-read my post, in the 2nd paragraph I say just that..
We're making the same point here.
Slots were used to release gas and X-Drilled holes reduce weight! This is the knowledge I've gathered form this and other forums over the years.

Hmm, I'm not sure about that weight reduction thing.. Rotor mass is great for absorbing heat, which is MUCH more detrimental to the whole system than rotational inertia.
I maintain that holes were drilled in rotors to provide an "escape route" where gas build-up could vent and keep pads in contact with the rotor.
The stots do just the same (as stated in my original post), and they also help deglazing the pads. Which is not needed either on a well matched rotor / pad material combination.
Bottom line, the fancy stuff is now mostly 'fo sho... It does look very good!
