To prevent dangling #[allow(unsafe_code)]s or #[allow(unused)] from existing, it might be good to replace these with #[expect(...)]. This will throw a warning if the lint does not apply. This is most applicable to unused, dead_code, and unsafe_code, but other lints also should be migrated to expect.
