There are pros/cons to both, I was just trying to highlight that even though the parachute reduces velocity of a crash it is still an uncontrolled descent and could still cause damage or injury. I have not seen where these events (flying off somewhere random and hovering) are happening to x-stars but I have seen battery will drop suddenly/quickly. At that point I would rather it crash like a rock to the ground on my flight path than drift off.
Hopefully the situation will never arise where the chute would deploy
and it sounds like you have safety in mind to begin with. Best of luck, please share your experience positive or negative so we all can learn and be more knowledgeable on the subject!
I would definitely consider getting one if applying for a waiver to fly directly over non-participants (actors, for example).
To get the waiver you need to demonstrate to the FAA how you will mitigate risks and perform the operation safely, that's how the waiver makes it safer. I'm sure there are some examples out there of granted waivers/coas (certificate of authorization) to learn what criteria is important.
