Yep, all agreed vilas - that is my understanding of it
A good system which works well. The ground speed remains impressively constant, and as you say, ground speed is what matters when landing.
The difficulty comes when an Ex Boeing pilot flying an Airbus FBW wants to pull speed to disable G/S mini and stop the speed target changing* But without the added safety factor this could leave the Airbus compromised.
*(Some get really nervous when G/S mini suddenly adds 25kts and the A/THR adds loads of thrust.)
