You forgot about Izzy's TDRI cameo, which is also well liked, contributed to the plot a lot despite Izzy appearing as herself for a short amount of time, continued her conflict with Chef and was the first interaction between 1st gen contestant and 2nd gen contestants ever.

Duncan's cameo is also liked, but he interacted with Chris and Chef only. And keep in mind the main prank was actually Chef's fault. For the same reasons (continuing some plots, but not contributing to the plot of the episode), Everyone's cameo is also a wildcard (although more likely to win).
