I thought they already had these specifically for avalanches, minus the drone. Some sort of tracking beacon that you can carry around, that will lead them to your body.
They do, and if you ski the alpine backcountry without one then you must have a death wish.
Avalanche safety is one use case where, as with defibrillators or hospital pagers, I think people will continue for a long time to use simple, rugged, and purpose-built devices with very low probability of failure rather than introducing a million new failure modes by using e.g. a cell phone or flying drone.
