The only place where I would not want any flex is a track bike for short races at the track.
Thing is, steel frames don't really flex enough to absorb much bump. I think people prefer steel or CF frames because they don't buzz from road vibration and leave your hands numb.
I've had a few steel frames, one made from butted cromo, one made from 0.6 mm thick Super Vitus 980 tubing (It's on ebay now under Gitane Tricolore).
A stiff aluminum bike with a CF fork simply has a great feel.
