The racers may have planned to have losing animations for when they reach 5th or lower. In the game's data are Peachette and Pauline's losing voice clips, as well as voice clips from characters that appear in Mario Kart 8 Deluxe (prior to the Booster Course Pass).

The final game has the racers appear neutral should the player end up in 5th place or lower.

Since Pauline and Peachette were included as among two of the final four characters in the Booster Course Pass, these unused voice clips may have been a deciding factor behind their inclusion in Mario Kart 8 Deluxe.
