> For me, the decision is clear: when I'm not able to make my own decisions turn everything off and let me die.

And what if you might be able to make decisions again tomorrow. Or the day after? Or in two weeks time.. ? These things are never all that 'clear'.

The underlying idea here seems to be that if there's some chance of full recovery, one should not wish to be let go.

Is it better for 100 families to live for years with a vegetative loved one with the most realistic hope being that a few to emerge profoundly affected and never their full selves again, or is it better for those hundred families to get to grieve?

The pain of a loved one's continued quasi-existence, plus the difficulty of their life if they ever are to recover, make it so that the compassionate personal choice is to say "once the best estimated probability of my recovering robustly is clearly below P%, let me go". The value of P is a decision to be made carefully, and with deep consideration for ourselves, our loved ones, and for all of humanity.

That's exactly why you write your own decision down, so other people don't have to live with making them for you.

In my written will I have defined a clear timeframe. If I have not recovered by a measurable amount (GCS) in a timeframe of 4 weeks, it's time for me to go.

Edit: note this might be different for you. You are the only one who can make that call. You can also decide that you want to be kept alive as long as possible. But then at least your loved ones know that that's what you wanted.

After a couple of months of coma they are pretty clear.

Each person should be able to make their own decisions. You seem to wish to be preserved on the off chance of improvement. GP (and I) would prefer to be let go.
