Oh, good lord no. The harder the effort or the sketchier the surface, the more I want a solid connection to the pedals. I do have to admit that, at least once a CX season I'll crash into a barrier because I can't get my foot out on a dismount, but that's usually from fatigue and/or lack of skills.
[edit]
There's no more requirement for toe clips or clipless pedals in road racing than there is for multiple gears.
