Would not the 3/16" steel bumpers which are not inherently designed to crumple just transfer the impact forces to the sensor through the mount points?
The crumple zone of our frame is between the bumper mounting points and the tube. Effectively it's a steel accordian. Remember what happened to Jason's envoy when it hit the tree? That's where it crumpled, and if it didn't give there I would bet that he could have had a hot airbag in his face.
By bolting the bumper directly to the sensors, or very close to them, you effectively get rid of the crumple that the airbag system is designed around. The only worry, as I think I said before was that it may give a false positive signal for airbag deployment at a lower speed accident than the airbag is really needed. Not a huge issue I don't think, but something to be aware of, especially if you drive like Jason.
