By removing the front bolt on one side, the axle is freed up for articulation.
The downside is that during heavy braking, only the radius arm that has both bolts can resist the rotation of the axle. This will increase the load on the bolts and the rubber bushes on that side radius arm.
I did a trip today that involved about 2 hrs total on main roads and there were no significant issues, but I wouldn't want to run like this for an extended period.
Off road is great, so a quick detachment pin will be good for mixed on/off road. For extended on road, the bolt will go back in.
