I've never been a fan of it, myself, nor of having the rest of the set balanced around it. Thematically speaking, the Hulk has his roaring, eye and vein popping, chest beating rampages, sure; but does Superman? J'onn J'onzz? Captain Marvel (either of them)? Rogue?
Heck, if we were starting from scratch, I'd probably make it the Brute inherent power.
(Also, I'd put KO Blow up there with Foot Stomp for "defining", even ahead of.)
