Considering that the planes are mostly full of leisure travellers anyways (business travel has largely gone the way of the do-do bird), this 'benefit' basically costs AC nothing. Heck, I'm surprised that any flight ever gets zero'ed out -- there's almost always certainly to be someone on any flight who will take an VDB compensation offer that is less than the full-Y fare.
Some fares allow for people to buy a ticket without confirmed segments. Again, usually very high fare buckets that even most SE's don't even buy anymore (most 'discount' fares require confirmation of all segments at the time of booking!). Priority waitlisting just means that if space becomes available, the segments are confirmed in preference to other customers who may also be on the same waitlist. Mostly its a holdover from the old days when there may only have been one flight a week to, say, Bangkok, discounting less prevalent, alliances non-existent, and the consequences of not getting on a flight literally meant that the remaining options were far less savoury.
"Back then", people bought a lot more full-Y or full-J tickets, often with multiple reservations (ie: a businessman might have made 2 or 3 reservations depending upon anticipated events during a trip), so the planes, at least on paper, appeared to have a lot more passengers on them than actually showed up. So waitlisting was actually quite common. Today, there's so many options for re-routing possible, and significant surveillance by the airlines for multiple overlapping reservations that this is not a tactic used by business travellers. An AC FA friend of mine, in the 80s, told me she used to book a parallel full-J reservation for each personal trip she took, cancelling (and refunding) the segments if she was able to get on the plane as a non-rev. This is why the industry had to turn significantly to overbooking -- not because an abundance of people were buying tickets and throwing them out, but rather, there was significant abuse of refundable tickets.
I would say I agree with this. It is somewhat of a holdover from the old days. Also - since the advent of electronic ticketing - reservations are now always linked to the ticket coupon. In the old days - you could just make a booking and have an open ticket - and show up pretty much when you want. There were often poor controls over duplicate bookings and the no-sho rate was very high. I can say that AC873 ex FRA used to have in the range of 50-75 daily no-shows on the old 747-200 that flew the route. Now you mostly deal with mis-connects.
As for priority waitlist - I believe that in a reservation there are two ticket status codes for waitlist. One is HL (regular) and I don't remember the other one - but there is a priority waitlist code that I have used a few times. I tend to use it when I am trying to make a change to another flight when there is no space in the booking class I am requesting. It gets queued in a priority waitlist and will normally clear on a priority basis. So - I would say I have used this but not for a while.
