The patches for 1.21.4 and 5 have been merged and I assume the mod is functional now, so is there anything stopping from the mod being packaged up and released on Modrinth?

@Ryhon0 you are a saint. BTW do you have plans to update it to 1.21.6 and perhaps by change fork Shulker Box Slot and Elytra Slot to work with your updated fork?

I'm not really familiar with this project's internals so I don't think I'd be able to update it to .6, but if someone else updates it and there's no official release from emily , I'll merge those changes into my fork and make a release for it.
As for other mods, I have no plans to fork them right now. You can ask the developers to target trinkets canary instead. It should be a drop in replacement
