We're not overly restrictive here. only BA mandates AP on at all times. True, switching FDs OFF on a daily basis would stand out.
W.r.t. the ILS generations' clash, no need to be so PC. MAN ILS should be achievable at all times. Might not be nice, or even inside the check standards on the first attempt in daring conditions, but the second one ought to end with a controlled landing from minima.
Less than that is inadequate - get up to speed in the remaining session time, and figure out how to show up abler on your next visit. 90% of people do, mostly just by staring at or behind the FDs during daily ops.
