The issue

In today's beta, zombies, husks, drowned, and zombie villagers were changed to use this absolute abomination of a shareable component. It's 1400 lines long and literally just lists as many items as possible. Here it is: https://pastebin.com/L45NB0zB

This is extremely unmaintainable and has the following issues:

• Impossible for packs to add/remove items without entirely overriding four separate entities
• Any new items added to vanilla or custom items will be excluded
• It doesn't even include all of the items in the game, it misses totally random ones like
  • boats
  • spawn eggs
  • axolotl/powder snow buckets
  • splash potions (even though normal and lingering potions are included)
  • cooked beef, leather horse armor, shields, snowballs, regular spider eyes, spyglasses, snowballs, string, sugar, totems, tropical fish, warped fungus on a stick, wheat, wheat seeds
  • all blocks (except for carved pumpkins, conduits, item frames, trapdoors, and doors which are included)
• goat_horn doesn't even use the minecraft namespace for some reason
• All of these items are using the old legacy IDs that should have been phased out
• These entity files are now literally more than 80% a single ridiculously huge component
