Has this been done for a reason? or have they just lost the hex nut and grub screw and bodged it with a nyloc nut?

Fairly standard modification, even did it on my own racing Lazers back in the day as it stays in place where the standard nut will fall off and disappear if it wasn't done up tightly or threadlocked, I got rid of the kit parts for better reliability. Considering how much power went through my touring car converted Lazer there is certainly no reliability concerns with a nyloc nut as mine went through about 6 years of racing every week without coming undone.
The standard grub screw in the nut setup is overcomplicated for what it is. The only advantage of the nut and screw is if you are running with the one way set up so it is free enough to allow the one way to work, but just tight enough to give some drag on the assembly so you get some front wheel braking. Good idea in theory but when you consider this drag to transfer some braking power to the front wheels has to be transferred between the alloy washer and the nut itself, and 1/4 of a turn is enough to go from loose to tight it's never going to happen in the real world. In reality as you are running with the one way either free or tight a normal nyloc nut does exactly the same job and is a lot simpler to adjust.
