My argument is that even if it were used correctly, it serves no purpose other than 1st and introduces a lot of extra overhead to go back and convert onlys to 1sts when someone appears a second time. We can't know if an appearance is going to be an only appearance but can be reasonably sure if something is a first appearance.

What is the justification for only being different from 1st?
