What Should Be Added or Changed?

Can u please implement IRecipeHandler
This will give support to crafttweaker replacing ingredients in recipes

Why Should This Be Done?

This will give modpack devs an easier time trying to fix all the duplicate ores/ingots/blocks/dust/...

easy but bad example:

Tin block takes 9 tin ingots.
I got several types of ingots in my pack but I only want 1 in the whole pack.
If i use the replacer from crafttweaker, i can just say replace every tin ingot with the 1 tin ingot I want.

better example:

A specific machine of a mod that doesn't use the forge tag (like forge:ingots:tin).
If I disable that tin ingot of that mod, that recipe is broken.
With the replacer, i can easily fix this because the disabled tin ingot gets replaced with the one I'm using.
