Just so - many of the reasons offered up in just this thread are rationalisations after the fact for following a convention. On the other hand, some reasons do have a cogent logic-driver, such as the Brucey dynamo explanation. Others are logic based on imaginary premises.
We humans do love to justify ourselves. Perhaps this is because we're told that we're responsible for everything we do? In practice, it's some long forgotten historical twitch that decides if we do this or that.
If that's the case (historical twitch puppeting) perhaps we should all be more sceptical of our everyday habits? I try to be, myself; but being an old dog - albeit one who likes new tricks - I like the old tricks a lot, as well as the comfort of my various well-used baskets. However, I may go to the bike shed now and swap the QRs around, on principle. Also I will point them in an unusual direction, such as forward. Why not?
