Would this support the Inspirations mod's cauldron brewing?

No, this is specifically for non-cauldrons, as cauldrons are already handled. If you want to see support for Inspirations mod's cauldron brewing, open an issue here or post about it in #suggestions on the Discord server.

Done for 1.20.4, but needs to be ported down.

• 1.20.2
• 1.20.1
• 1.19.4
• 1.19.3
• 1.19.2
• 1.18.2

This is done, and will be in the next version of ImmersiveMC (1.5.0 beta 2)!
