Not an expert, but I suspect for many there are warning signs that someone may die in their sleep (or exercising, or ???) long before the heart finally quits. This seems like a great way to monitor for that.

when I'm old and going to die, "in my sleep" would be top of the list of ways I would want to go, (during sex is likely not going to be an option)

		May we all be so lucky but "old" is relative in this case. An acquaintance did just that... in his 50's :/

		If it’s during sex, would you want your sex partner to also die at the same time? Seems like it would be a troubling experience for the other person.

I’m an EMT, so not the deepest level of knowledge, but certain progressive things that will kill you (such as sepsis) would show noticeable trending in basic vitals like heart rate and respiratory rate. And sepsis is also common in geriatrics (catheter / surgery / G tube -> infection -> sepsis)
