To quote pokemon

Whenever possible, avoid those, even if it restricts design

Charizard, Expedition 039 (For Position Only) Average Price : $8,000.00 Description: The Charizard Expedition 039 (For Position Only) card is a rare artifact from the Pokmon TCGs early days

Players could still get and play unserialized versions of the card to play, which is to some extent the same here as each of the chocobo is the same color, but while the art used for the One Ring cards would be different, it was still just the same ring, just with a different picture

Although, by how few recover cards there are and by how the keyword was never used in other sets, I think it's safe to assume that maybe even the designers had their doubts about this particular keyword
