Marriott’s new loyalty program doesn’t offer a lifetime status level higher than 50 nights. The old Starwood program didn’t either. However the old Marriott Rewards program offered lifetime 75 night elite status, and those who achieved that status in the legacy Marriott program, got to keep it.
Marriott carved out an exception that let some Starwood members earn it too — but said it could never be earned after 2018. That turns out not to be quite correct.
