Those will obviously chew into the dropout and can’t see a good reason to use them.

It’s painted metal and your bolting something up against it with a good amount of force, you can’t expect it to stay pristine. If it bothers you that much get a an aluminum frame with steel inserts, or a steel frame with the paint removed from the dropout area, or remove said paint along the dropout as I suggested, OR install the wheel and never ever change your cog and make sure to always install wheel in same spot so missing paint is hidden under the nut.
