This is interesting but very, very ahead of its time. I know a couple of surgeons who have done a lot of research to prove that liver with a moderate degree of steatosis (fatty liver) is still viable as grafts, because every now and then they have had to cancel a scheduled transplant because the donor liver turned out to be more fatty than the standards would allow. They are optimistic but it would still take anywhere between 5-20 years for enough evidence to accumulate and change the view of regulators.
