wobbly rear sprocket on coaster brake hub

Does anyone have any experience with the rear sprockets on a shimano single speed coaster hub wobbling or coming loose?.

Mine is starting to do this but the bike mechanic told me that as long as it doesn't slip on me that I'm good.

What is causing this and what are the solutions if it becomes worse?.

I know that the sprocket for these hubs have 3 rivits around the ring so maybe those are wearing down?.

other sprockets such as mtb have more rivits so maybe that means longer life there.

Also they are steel so they could strip down and warp over time.

it hasn't slipped until it does and I would rather not be on it when and if that happened, but you'll never know unless you are the one powering it.

should I be concerned?.

It has some play when I wiggle it with my finger
