A small number of these can accrue WP (Emerald) status with QF whereas in CX / FinnAir / Other Programs, your actual mileage flown and the fare class booked might see you lucky to earn Ruby (or worst case nothing at all

)
Every program has ways of "gaming" the system. There are plenty of programs where it's based entirely on mileage, however people fly on very cheap fares, generating little profit for the airline - just look at the Mileage Run forum. At least SCs go someway towards recognising that certain passengers are more valuable to the company.
As for MEL/SYD in J - you need to do 30 such trips to retain Plat (and 35 to make plat). I don't consider that to be a "small number"
