I'm not particularly concerned if people check out my ageing body in the raw. Nothing personal anybody, but looking at a parade of frequent flyers is not likely to be an arousal-fest.
However, younger people are more likely to be gazed at with erotic intent. Likewise celebrities, possibly for other reasons.
I'm not entirely convinced that the generic body shape will be the only option available to the operator. My guess is that it would be a bit of a safeguard to prevent your security shift resembling that of the shower attendant at the old folks home.

As others have pointed out, a bomber can walk straight into the middle of the checkin queue and blow himself up, or leave a bag unattended for the few seconds needed to get out of range of the blast. Pick your spot well and hundreds die. Every airport in Australia, if not the world, would be shut down until someone works out a solution.
Crowded commuter trains, sporting events, bus terminals, shopping centres, carols by candlelight... We can't make everything 100% secure without totally destroying our freedoms.
