That's why they've been well received.
For example, consider a man who becomes incapable following a stroke and is in the same situation as a person suffering from a neurocognitive disorder, by which I mean that his condition is grievous and incurable, that he is experiencing what he deems intolerable suffering and so on. That case must definitely be distinguished from those that are the subject of the advance medical directives provided for under Quebec's Act respecting end-of-life care. I think those are two completely different things.
