JarJar de-duplication not working for Fabric+NeoForge builds

When using Forgix together with a Fabric+NeoForge+Architectury Loom multi-loader setup, jar-in-jar duplication does not work as intended.
This is likely due to Fabric injecting a `fabric.mod.json` into dependencies while NeoForge does not, resulting in dependency JARs becoming not identical.
Is it a Forgix issue or if there is a certain project setup that would prevent this?
