If you think about multi-class bookings, like for P it's easy to say connector is in full J any time.
But for Premium Economy fares with a connecting Economy feeder, you have to book the feeder into something, and using Y inventory is probably not the best idea given that Y can be a lot more expensive than a cheap PE fare.
