Fabric API provides the fabric mod id for mods still relying the old id. FFAPI does not do this, causing mods that work natively on Fabric to crash while looking for the fabric dependency.

Forge obviously handles mods differently, but it would be useful if FFAPI could either provide a stub mod for fabric, similar to how Embeddium provides one for Rubidium, or for FFAPI or Connector to override this when transforming the mod.

FFAPI currently uses a mod alias feature in Forgified Fabric Loader to provide alternative mod ids to Fabric mods. It's possible the feature is not working as expected.

Can you please provide a few example mods that are affected by this issue?

Nevermind, works fine in my testing. Someone in the Discord mentioned it wasn't working with Astrocraft but there must be something different about their setup. They might've even been using Fabric API.
