I know Anvil doesn't support K2 yet, but I was surprised that this error led to a `TODO()` inside kotlin that doesnt seem to have a youtrack associated:

e: kotlin.NotImplementedError: An operation is not implemented: Missing package reporting

That's not surprising, a lot of IR APIs reach into new FIR APIs under the hood that aren't (or won't be) fully supported

I didn't get this error with the last EAP, but that could be due to the other K2 blockers i reported and it just never got this far before 😄

Using descriptors in IR plugins is deprecated Actually, moduleDescriptor in module fragment is the only descriptor property which is not marked with corresponding opt-in I'll replace this TODO with an exception with some proper message
