FAPI does not seem to see the custom pack.mcmeta in the mod's root. This is a problem since pack.mcmeta provides several features that help modders (features, file filtering, overlays, etc.)

For example, this pack.mcmeta will make it impossible to get the Netherite Ingot recipe when a player obtains the Netherite Scrap. This works in an empty world data pack, but does not work in Fabric
pack.mcmeta.zip

Features and filtering are not relevant to mod packs.

filtering are not relevant to mod packs.

Would there be a usecase for a mod to filter out some of vanilla's resources? I think this is whats requested here.

Features and filtering are not relevant to mod packs.

Hm? Well, I disagree about file filtering. I think it is convenient for modders
