It certainly is the flare which eats up the runway, holding off or using aerodynamic braking is multiple times less effective than braking. I’m not saying you should land the aircraft with too much energy either, the post you are responding to (from 2020) was about the argument whether you should land the aircraft in a “full stall”, apparently this is more a matter of definition and US people seem to use this term to describe touching down on the horn. I wouldn’t call that a full stall, a full stall would mean passing the critical angle of attack with airflow separating. I argue that its unnecessary to hold the aircraft off until you have the stick fully into your stomach until you can’t hold it off any longer. Its a waste of runway. When landing attitude is reached (whatever that may be for a particular aircraft type) there is no point in holding off, touch down with a safe vertical rate, de-rotate and the aircraft is not flying anymore.
