The slightest increase of probability having to report or explain themselves in the office is a main reason to keep the autopilot engaged to nearly the flare to landing!
Yes,FDM has a lot to answer for.It gives with one hand and takes away with the other,a true double-edged sword.It enforces stable approach criteria but makes the pilot a "button-pusher" or that CRM-derived nonsense word,"flight manager".If your airline has anything like "Use of AP recommended at 400'" or "no hand-flying above 10000'" or "FD use mandatory",they're doing you no favors.
