Issue description

refmap file reference is hardcoded into the mixin json file but no refmap file is provided (in NeoForge release).

If a refmap is not required, and the chosen toolchain doesn't handle dynamic refmap entries, and it is still desirable to hardcode for the unnecessary refmap, then an empty refmap should be provided when refmaps are not needed.

I'd be happy to merge a pull request for this. But honestly, I don't want to spend my time on something like this

Yeah, but I want to keep it as consistent with fabric as possible

If a refmap is not required, and the chosen toolchain doesn't handle dynamic refmap entries, and it is still desirable to hardcode for the unnecessary refmap, then an empty refmap should be provided when refmaps are not needed.

Then you need to handle the invalid configuration by either making it valid with a refmap on platforms that dont need one, or removing the refmap reference here and supplying it programmatically in a mixin config plugin with a platform check

What is the consequence?

unnecessary errors in logs
