the Fl400S is NOT disco'd at all. they actually started using it again on some apps that took the 3.5L V6 in the 2009ish range.
With no intent to get into the crossfire between 400S vs 910S apps, I will note that both filters are still widely stocked on vendors shelves (Walmart, AutoZone, etc.). So, there must still be a demand for both. Kinda reminds me of the FL-820S & FL-500S scenario that has/had some owners/installers confused
when Ford did the switcheroo from one to the other on the 3.0 V6 (e.g. 2009 model year Fusions).
