Can FirSupertypeGenerationExtension add super classes, i.e. not interfaces? I'm adding a superclass, which results in FIR that looks like class TestModule : R|kotlin/Any|, R|dev/rnett/lattice/module/BaseModule|, IR CLASS CLASS name:TestModule modality:FINAL visibility:public superTypes:[kotlin.Any; dev.rnett.lattice.module.BaseModule], and the JVM bytecode class test/basic/TestModule {, with only Object as the supertype. I could probably do some massaging in the IR to remove Any but that seems pretty hacky

I am able to extend an interface, and implement it in FIR/IR. https://github.com/nomisRev/ktor-typed/blob/main/compiler-plugin/src/io/github/nomisrev/typedapi/compiler/plugin/fir/AddSupertypeExtension.kt

Worked in 2.1.20, and 2.2.0

Yeah, I would expect an interface to work. But I'm trying to add a superclass that's an abstract class, and it's not working. I'm guessing because it still gets Any
