It has worked for me when I have needed it - probably twice in the past 10 years. I don't think there is any automatic system that scoops up cancelled bookings into a waitlist.
My preference is to ensure I am on the flight I want soonest, and also it is just 'good form' to release the 'held' seat as soon as possible so another pax could access it.
