Even various key provisions of the Patriot Act

usually they are unceremoniously reauthorized by Congress because its just too much to think about

sometimes Congress forgets (or the related lobbyist forgot/couldnt get a lunch date with the co-sponsor)

but this isn't a perfect system its just more case load in practice that no individual person is aware of

I personally cant think of any debate that occurred on an upcoming sunset provision where people consciously said “yeah that has no more applicability let it expire” or “we have to reauthorize this or itll be a disaster” its just nobody has time to think about it so they rubber stamp it in the annual budget reconciliation bill to keep the government open
