Yes.
That design, and appropriate torque, would lock the pedal to the crank solidly enough to prevent precession.

Well, if the average buyer thinks that the current solution is good enough(and let's face it, crank/pedal failures aren't that common), why would he spend money on a fix that won't improve his ride in any way?
"it's better, but in a way you'll most likely never benefit from" isn't gonna look particularly compelling in the catalogue.
It's like with spoke lengths and hubs. Most rear wheels will use a 2 mm longer spoke on the non-drive side, which could have easily been avoided by designing a hub flange that's 2 mm larger. I'd rather have a wheelset that only took one spoke length than a chamfered pedal spindle.
