Interesting discussion. I currently fly the Airbus and find the FPV very useful to aid accurate manual flight.
I'll be on the 737 Max in a few years and am glad to hear that the feature will still be available.
Having flown both types the FPV has more uses on the A320 etc as the a/c (under normal law) is trajectory stable. Also on the Airbus there is a scale on the horizon on the Attitude Indicator and the desired track can be set showing as an index - these facilities are not available on the B737 NG but maybe the Max will be different?
