What goes unmentioned is the fact that your family gets stuck with the bill if it turns out that your organs aren't good enough to be donated.
All the time and resources keeping the body in good enough shape until the hospital is ready to remove the organs are billed to the family of the deceased if it turns out that the organs aren't acceptable. So, on top of your family mourning their incredible loss and stressing about the medical bills that have already accrued, they are told "thanks for signing up to be a donor but it didn't work out so now you owe us an additional $200k."
