Yes, but they should. Brake fluid is hygroscopic and will absorb
moisture out of the air over time, and you still want to deep bleed
the brakes with fresh fluid to effectively change it occasionally.

Though I would never stretch it to 150K, do it every time the
calipers are rebuilt or other major brake work is done to the car, in
the 30K to 60K range.
