There is a certainly a grass-roots movement to eliminate 3C medicals for non-commercial flying and simply require a valid driver's license instead (a la LSA). I suspect this has a decent chance of becoming reality.
Do you have a link to the new rule on international ops? I thought that ICAO required one pilot under 60, which was why the FAA mandated that for international?
Given improved blood-sugar monitoring and insulin delivery technology, I can see how it might make more sense now than in the past, but I haven't heard anything about a change.
