That's exactly the point I was countering.

There's simply no (zero) need for anything to prevent sprockets from rotating or being installed without the front edges fully butted against the spline. The first time they're used the chain will pull them forward as far as possible. Once there, they'll obey Newton's first law and stay put.

As I said, the wide spline is for orientation and ONLY for that.
