Well as far as I know, Profiles have a single keyway and quite a few
people including myself are having problems with slop in the keyway.

Doesn't it make so much more sence to simply spline the axle the whole
way through? My ideal hub is an axle splined either the whole way
through with spacers between the (also splined) flanges, or the axle
splined through to where the flanges are with a little lip or something
to keep them in place.

the hub

Thats right, the splined axle for the KH/Onza that is used for attaching
the cranks also interfaces with each flange disc of the hollow centre
drum, so there's no need for a keyway. Makes the hub much lighter as
well.
