Looks real to me.

I would argue that we are in the real world and that our application has parameters that support the common use of 7075 anodized hex shaft. I believe the best practice not to make a blanket statement about material usage and instead to state it's usefulness in terms of our application.

Saying round shaft is always inferior isn't true. Even in FRC there are times when we may be better served with round shaft. I would never tell my students to always use hex or round shaft or aluminum or steel. I train them to pick the best thing for that application. If we have sponsor that will buy half a robots worth of hardware from mcmaster and machine shop that doesn't have hex broaches then round shaft might be a better choice that time around.

Oh and...

4. round shaft couplings and collars are easier to produce (again depending on required tolerances/features)
