Create a new world

Add a NBT hacky data pack, try to convert it to use enchantment/

Nothing seems to happens on /reload, search changelogs, can't figure out what I've done wrong.

Shut it down, return later.

World is now experimental , but the (what I thought were) failed attempts are now present with /enchant.

Unloading datapack does not remove the test enchantments.

Expected enchantments to be in that list

Read through the changelogs and wiki again, the only reference to experimental feature was "All Features from the experimental 1.21 pack have been moved to vanilla". and the trader rebalance experiment. World was not created with either trader rebalance or bundles.
