It's complicated. Some theoretical and practical issues are extremely complex and remain unresolved. How do you differentiate suicide from euthanasia? How do you determine the irremediability of a state? You have to examine those questions. This has been put off for some years now, and we still aren't able to resolve these issues.
That's why we say it will take a long time for us to come up with answers and solutions so we can say we need such and such safeguard.
