As far as the steep approach mod is concerned,, sure, you don't need it at the moment, but ten to one that flybe decide next week that LCY is the centre of the known universe (as it was a few years ago), and deeply regret not having all the aircraft modded... they certainly did last time!
Since British Airways own a very sizeable chunk of Flybe, I doubt that's going to happen any time soon!
So it looks logical to me!
