That’s normal. The freehub body is softer than the cogs in the cassette.

Nope. It’s totally fine.

Yes, as the others already said, the freewheel bodies are mostly made of aluminum and thus softer than the sprockets, which are mostly steel. some manufacturers offer steel freewheels, so the sprockets should not eat in so much.

This is a common thing in Shimano type freewheel bodies if they are made from aluminium, and if you use a cassette that has loose cogs.
The splines are not deep enough to be made out of aluminium, causing the cogs will bite into the freewheel body. I think Shimano freewheel bodies are still made of steel or titanium for this reason.
It’s not really a huge problem, although if it gets bad enough it may make it difficult to remove the cassette.

I’ve had alu freehubs in far worse states that were still functional (mostly Hope). Never had one break due to scoring from the cassette.
Installing a cassette with as few separate cogs as possible can reduce the effect. Steel freehubs are tougher and will better resist the cassette biting in.

Looks fine, very normal with a alloy body
She’s still good to go, Captain, full send ahead!
