Edited as saw your update as yes I read it as the skin wraps due to the self adhesive.
My view on skin wraps:
When I had my Sony A7iii with Sony 200-600mm attached it rubbed against me on the zoo one day, and caused significant paint rub just on one day. Hence I have used such wraps since. Can get them fairly cheaply from places like Aliexpress. It means if you ever want to sell a lens or camera, they look like brand new once you take the wrap off. Therefore they generally more than pay for themselves.
My view on the cloth wraps that you've confirmed you are referring to:
I agree. I think may only be useful if you some reason you aren't using a proper camera bag; but obviously still don't provide the same protection as a proper camera bag does.
