From how I understand it, track one is for children or people who have a disease they are dying from, and that would allow them a yes or no for medical aid in dying. Our euthanasia law requires hopeless and unbearable suffering, which means that there's no good outcome possible and that there is certainty of the diagnosis.
Those seven cases I described were all somatically ill children who were dying, and it was a shortening of the death process they had asked for and received. I would say that without a track one condition, it would be more difficult to envision a good regulation.
