Does KMM support Kotlin 1.8? Asking because the plugin is not available for the latest Android Studio Canary release and it's not listed here either https://kotlinlang.org/docs/multiplatform-mobile-plugin-releases.html#release-details.

I don't know the official answer, but anecdotally it's yes -- I'm working on a KMM app and just upgraded to Kotlin 1.8 this week without issue. The only caveat is that I didn't switch to the new source set layout yet because I'm only running stable Android Studio (2022.1.1) which doesn't support it per the note at https://kotlinlang.org/docs/whatsnew18.html#configuration-and-setup
