Pagan (Retro adventure character) default avatar option works, but not shown in UI

Hey hey!

I'm the maintainer of Auto Avatars, an add-on for Thunderbird. I had a select menu to choose a default avatar for contacts, but I've noticed a change between my options and what's on the website today.

There used to be an option with the keyword pagan and name Retro adventure character. The option still works, but isn't visible on the website.

Is the option deprecated/dropped, or could it be been forgotten during a UI revamp perhaps?
