Hi. Is ksp still tied to jvm or is it finally mpp? Also is it in the same niche of tooling as arrow-meta?

not mpp yet. it is in the planning but not high priority right now.

A bit more context: we do support the expect/actual keywords as the main language features needed to support MPP. However, we don't have compiler plugin integration to Kotlin/JS or Kotlin/Native yet. Our main consideration here is the new Frontend IR work and if we should wait on that to land or add extension point to the current Frontend to hook in to the Kotlin/JS and Kotlin/Native compilers. We're actively evaluating the options and figuring out when to plan this work, but it is absolutely something we do want to support.
