Several threads on PPRune about this.

Manufacturers do not 'recommend' therefore you may be on 'sticky' ground.
I have 3 times seen a high flare manoeuvre and A/T 'kick in' - it can, Denti. It can be hilarious to watch

In its favour is the g/a (plus possible avoidance of a THY at AMS if all is working). Without A/T on the g/a the nitpickers once told me you
must apply TOGA with manual throttle rather than using a reduced power as per a single press reduced setting.
