Never ceases to amaze me the hysteria that get's set off in Aus when a rule identical to how the rest of the world has operated for decades is introduced.
Final reserve is just that, and if you have to use it it's because you've screwed the pooch and is an emergency. That doesn't mean don't use some of it, it means you are in an emergency situation and need to act accordingly. Considering all options including an out landing- something people used to do as routine (and glider pilots still do)- is just good airmanship.
