Your comment made me think of Netflix' "Chaos Monkey" -- the system which randomly disrupts PRODUCTION systems:

Perhaps eliminating restrictions on electronics use would have a similar effect. What if the FAA started out by allowing use on a select number of flights where the pilots were highly trained and aware of the supposed risks? Over time, restrictions could be lifted more broadly presuming these initial experiments showed no cause for concern.
