You've always needed an explicit clearance to taxi across runways.

Ron, This is not my understanding. Without an explicit "hold short", an

runways that happen to be on the taxi route.

Yup. AIM 4-3-18a5. Ground control sometimes gets annoyed if you ask for
confirmation before crossing an inactive runway on your way to takeoff.
