It's not a big problem right now but projects with kotlin multiplatform android modules, most of the ones i looked at assumed your android sub module was just using the jvm target/preset and probably rightfully so as the official example on
https://kotlinlang.org/docs/tutorials/native/mpp-ios-android.html lists this as what you do to get started, but if you try adding a library to the project that assumes android what you get when you try to run is the core module just erroring out and throwing unresolved reference errors because it's missing the actual classes/functions in android/jvm but that doesn't import/compile properly and left me very confused why some libraries just didnt' seem to work for some reason
