Once 421 is merged, my understanding is that KSP could do a step forward towards KMP projects by starting to support multiple jvm targets in the same project, as in:

kotlin {
    jvm()
    jvm("foo")
}

Is this on the roadmap? One solution could be creating per-target ksp configurations like

kspJvmFoo

, inheriting from the root

ksp

. I'm happy to work on a PR if the team agrees with the plan.

Yes, this is on the roadmap. We planned most of multiplatform tasks near / after Kotlin 1.5.20. Please feel free to send PRs,
