Your objection to Only only really applies to new comics. When I'm indexing an old Earth-Two, Earth-One or New Earth comic (like I was with today) and I add Only to a character (like I did to Roberta the Girl Wonder (Mary Wills)), I am pretty confident that it's OK. Even if someone introduces a new Roberta (which they should), it would be the Prime Earth Roberta. The Earth-Two Roberta will still have just the one appearance,
