There simply is no reason for a passenger to risk his funds to "help" CX when CX calculates no shows into its RM/IM algorithms and overbooks to deal with the issue (to the extent that the flight is even full now).
I'm just saying, that way, you can maximise the chance the flight will be cancelled and thus be eligible for a refund without penalty, or in case the situation changes again, to use the remaining coupon.
