The sieve does not have any input, and I just can delete the output of the sieve. Plz add an input of the sieve and that I can delete the input and change the recipe.

I want to remove by input.
For example,
<recipetype:exnihilosequentia:sieve>.removeRecipeByInput(<item:minecraft:gravel>) to remove all sieve recipes that the input is gravel. (to remove all ore piece outputs)
But your recipe classes don't override IRecipe#getIngredient, CraftTweaker thinks your recipes don't have input, so it can't remove anything.
The method you posted is remove by output, I certainly can use it to remove recipes. But I have to list all ore pieces. It is annoying.

well, the title isn't that clear, neither is the description. i reopen the issue as i can't resolve that rn

just for my information: does this issue still exists? in 1.16 and 1.18 version?

Sorry for delay, this issue still exists in version 1.16-20220530-185402 and 1.18.2-20220714-011314.

we'll won't fix that for 1.16 as we decided to make that last version final. your PR for 1.18 looks promising tho.

I think we simply can't remove recipes rn. When I try to remove any recipe, it says "No such member: removeRecipe".

Yes it's not possible until the PR for 1.18 will be merged.
