Minecraft Discontinued Features Wiki:Needed Pages

These are known discontinued features that currently have no wiki page on them. Feel free to add features that are missing or remove ones that have been created (blue link if it uses same name). Please do not create a blank or mostly empty page about these subjects, instead try to add at least a decent amount of information to begin the page and add the template if necessary. Also, keep in mind that the suggested page titles may not always be the best names. More info about some features can be found under same links on version pages.

Entities
https://bugs.mojang.com/browse/MC-126091

 * Persistent Zombified Piglin and Persistent Zoglin

 * Multiple Wandering Traders

 * Waterlogged Falling Scaffold‏‎
 * Zombie Pigman Villager - In 12w32a, zombie pigmen would spawn missing part of their skull texture. This signified the IsVillager tag, and a profession. This pigman is possible to be cured
 * Villagers In The Nether Pre 12w34a - This requires zombie pigmen from before 12w32a to be updated to 12w32a, at which point they will convert to villagers due to a presumed curing bug
 * Baby Piglin Holding Leather - Removed in 20w45a
 * Cod, Salmon and Puffer fish mobs have a health tag of 20 in 18w08b and 18w09a, was changed to 3 in 18w10a.
 * chests, furnaces, dispensers, carved/non-carved pumpkins, and logs held by endermen will keep their orientation when updated to 1.16.5 (likely also in all previous versions). Also, jukebox save their has_record block state (though not the record itself).
 * Nameless Killer Rabbits - Killer rabbits from 14w27a or 14w27b are discontinued if updated to 14w28a to 14w33c. The rabbits will gain the name of the destination version in 14w34a+ and so this feature can not be kept past that point.
 * Named Non-PersistenceRequired Killer Rabbits - Updating nameless killer rabbits to 1.8 to 17w50a (1.13 snapshot) in different languages causes the literal string name of the rabbit to change (not translation string). For example, a nameless killer rabbit updated to 1.12.2 with Español (España) will cause it's name to become "El conejo asesino" with PersistenceRequired still set to 0. Utilizing resource packs, this maydoes allow their name to be changed to anything, with other discontinued combinations including nameless, all space, § character, or longer than possible.
 * Broken Translation String Killer Rabbit - Updating nameless killer rabbits to 18w01a (1.13 snapshot) will cause it to gain the translation string {"translate":"entity.KillerBunny.name"} instead of {"translate":"entity.minecraft.killer_bunny"}. This translation string will work in 18w01a, but upon upgrading it to later versions will display "entity.KillerBunny.name" and retain its discontinued translate NBT.
 * Discovered endermen holding powered noteblocks. When upgrading an enderman holding DV 0 noteblocks to 17w47a, they would be holding powered=true noteblocks. At some point before 1.16.5, this was changed to powered=false.
