Since the stoning has ceased, perhaps it's good courtesy to return some pieces for another round of throws:

Airbus FBW has a reactive auto-trim, hence there always is displacement due to pitch/power couple. Can't be flown hands-off although the deviation is small. I'm also told that for landing at 100' RA that feature stops completely for the A330.

I think the passengers of AF447 wish they had a pilot who would pitch for speed first, instead of firewalling the thrustlevers. A330.

I think the owners of EK521 wish they trained the pilot to use thrust forward to climb and vice-versa. B777.

There are many non-jet A/C where there is no pitch-power couple, ATR to name one. Using power to manoeuvre in pitch is pointless, and insisting not only silly but just would not work. On those, yes.

On a machine with a decent power-pitch couple, using pitch (elevator) for V/S and only then thurst for speed is sloppy. But also very easy as the PFD tells you exactly that. Flight director command first, and later the speed trend arrow. CoM?
