They're cheaper, easy to DIY, fit standard bearings, hubs etc.

Hex shafts make assembly a lot easier. No need to deal with finicky keys. Hex is just as cheap as key shaft. It's still very easy to do in shop, as long as you have a lathe(many teams do). It's true that hex shaft does not fit standard bearings, but many times you can round the ends of the shaft. We have bought boraches for 3/8" and 1/2" hex, so we can hex anything we want.
