This should not cause any problems functionally.

I could have misread the OP as well so you may be correct.

I read it and was influenced by the photo, which shows the cup only partly pressed in. Rereading it, and looking more closely at the photo, I agree that he's likely talking about the OD chamfer on the head cup which is of no consequence.

A drop of touchup paint or a smear of stiff grease to cover the exposed bare metal on the face of the head tube is all that's needed.
