Device that initiates an autopilot goto for singlehanded man overboard?

Actually it is quite doable with existing hardware, just need some lines of code. You fall off, AIS beacon tells boat. It fires the engine and circles back, shifting to neutral when it gets close. Could rinse and repeat if it drifts away again. You're still going to die, because even if it gets within 50 feet you won't be able to close that 50 ft, or climb back aboard.
On the liability question, Raymarine at least has already answered this: if you tell the AP to follow a route, all it will do is alarm when it hits a waypoint/course change, you have to confirm the course change by hitting a button. The AP will not make changes on its own. Because they have lawyers.

As mentioned the NKE will set up tot go head to wind if AP remote or dedicated fob goes out of range (50m). It can also send a NMEA signal so you can for instance set it up to trigger a VHF DSC distress call. Am pretty sure it could be configured to trigger an AIS MOB signal too

Saw it suggested here once that the boat ejects the life raft in the event of a POB. Seems like a valid solution next to staying on the boat.
The MOB is even less likely to be able to catch a liferaft, blowing downwind at 10 knots, than the boat forereaching with the AP doing it's best - but failing - to keep it head to wind.
You can actually test this stuff. Jump in the water one fine day with foulies and let the PLB explode. Then measure your speed swimming with a GPS over say 1/4 mile. Next, on a nice 20 knot day trim the sails for speed then hit the AP head to wind. Wait till it settles however it's going to and check the GPS speed. Or heaving to. Or an inflated liferaft. See how those two match up.
My bet is that will convince you hang on a little tighter when you move about the deck.

Always best to stay on the boat but shit happens. Pretty sure no one plans to end up in the water.

I have had some difficulty catching the boat after going for a swim while at anchor. The premise of this thread is ridiculous: The likelihood of falling over while becalmed is minuscule.
I'm in the camp of those who believe it's best to avoid involuntary swimming while single hand sailing (or no matter the size of the crew). I guess conditions when one falls overboard are not a calm Sunday afternoon near cost. However any additional security measure is always welcome (like what NKE offers).
And I've come across this today:

Best to use somekinda life harness jet pack
Expensive but versatile since it could replace the tender for when you need to zip ashore to the pub for a cold one
