Suggestion

This suggestion will track elements of Skript code that should be removed as we drop support for various Minecraft versions.
2.8/2.9 supports 1.13+, and 2.10 supports 1.18+, so this issue will have a section for <1.13 legacy code and <1.18 legacy code.

This is by no means comprehensive, I'm mainly tracking the major bits.

I've looked through the files in order up to the ch.njol.skript.entity package.

Why?

To help keep track of elements of Skript that aren't needed anymore and that can and should be reworked to be simpler and more modern.

Other

<1.13 Legacy code

• ItemData: OldItemData and other 1.13 compats
• BlockCompat: possibly useful to keep around in case of future major change, but I find that unlikely
• BurgerHelper
• PassengerUtils
• BukkitClasses: getEntity(UUID) method check
• Syntaxes that can have checks removed / docs updated:
  • CondHasResourcePack
  • CondIgnitionProcess
  • CondIsFuel
  • CondIsInteractable
  • CondIsPassable
  • CondIsSheared (doesn't have a 1.13 condition check)
  • CondIsSwimming
  • CondIsUnbreakable (doesn't have a 1.13 condition check)
  • EffExplodeCreeper (still needs paper check)
  • EffLoadServerIcon (still needs paper check)
  • EffMakeFly
  • EffPlayerVisibility
  • EffSendBlockChange
  • EffSendTitle

<1.17 Legacy code

• EntityUtils: Age-related methods can be simplified
• ItemUtils: isAir() method check
