That sounds like a very ambitious goal. If the GC is itself a Scala object, it would have to somehow deal with *itself* and its dependencies in a very very...

That still sounds like a lot of effort, and resulting in pretty fragile code. What is the point, here? What actual benefit is this supposed to provide?

SIMD support should probably be co-designed with Scala.js, as SIMD.js is coming.

SIMD.js has been abandoned by engine implementors. Efforts in that area have entirely moved to Wasm. So nothing's going to happen in Scala.js.

> From a build perspective, would it be ok to just move `clib` and `posixlib` tests directly into the `test` directories of those projects? No, that is going to be...

Use of reflection has a number of downsides. Why not use a factory function in the Config instead? It seems the functionality of this "plugin" is very specific, given its...

This can already be configured with the `withClang()` method of `nativeConfig`. There's no need to introduce more environment variables.

> Currently, only -reflect, -cli & -testkit are published with the full Scala version (-rules & -core are not, even though -rules does use `scala.reflect.internal`). From my understanding, the [rationale...

That's a *massive* run-time behavior change for a lot of code. It's going to break so many things. I really don't we should do that in a minor version, and...
