Just tested it again with my LaCie 9223 1TB with USB ID 059f:1070 on USB3 xhci ports of an ASUS Z-170 board and a HP EliteBook 820 G1.
It works now as expected on: F24: 4.8.16-200.fc24.x86_64 F25: 4.9.3-200.fc25.x86_64
Drive shuts down and disconnects from USB port after selecting "safely remove drive" on MATE desktop and it does not spin up again.
I also tested an older LaCie USB 2.0 drive and it still works as well.
