Actually, if drones are anything to go by, you can engineer a lot of redundancy if you have 6/8/10+ motor/prop combos. As these aircraft are mostly FBW by necessity (no human could balance the multiple power units), you can build in algorithms to cope with the loss of several power units. Even if you don’t have the thrust to stay up, it can be a controlled descent.
If you were really worried you could fit a BRS (or parasail)...
