...Unless said kernel relies upon "unstable" Rust features that are treated differently in different compiler revisions.

(And correct me if I'm wrong, but there are still a pile of unstable-isms in mainline R4L right now. In time that number will presumably continue to go down but it's quite reasonable expect to occasionally go back up for new/optional Linux features)
