Describe the solution you'd like
It would be cool if there was a config file for disabling crafting recipes and items.
I see it as being a json/json5 file with a structure that's something like this:

{
    // Recipes to hide
    "recipes": {
        "namespace": ["item_recipe1", "item_recipe2"]
    },
    // Items to hide
    "items": {
        "namespace": ["item1", "item2"]
    }
}

Additional context
I make a modpack and I disable a lot of things with Fabrication's yeet recipe feature, which removes the recipes but items still show up in REI. I kind of only want to hide items, but hiding recipes would be cool if I were to make a super-duper secret recipe for an item that only the coolest could unravel.

You can currently do this with KubeJS. Although it would be a good feature for REI.

KubeJS devs don't want to do 1.17 version

What do you mean? I'm using the 1.17 version and it works just fine

Can you give a link?

It still would be good to have this implemented in the mod since not everyone knows how to use KubeJS.

Disabling items are doing with the base mod with Manual Filtering, scroll to the bottom of REI config menu. Doing so will also hide appropriate recipes.
