Kotlin's jvm-abi-gen plugin can generate header jars similar to the turbine output for java sources, which can be used to avoid recompiling downstream modules when the ABI hasn't changed. Unlike turbine, the plugin runs as part of the main kotlinc invocation, so it doesn't allow the downstream modules to start compiling any sooner. A future possible optimization is to use turbine to compile the kapt stubs, at least for the kotlin+annotation processor modules that already generate them, which would allow compiling downstream modules before invoking kotlinc or javac, as well as invoking kotlinc and javac in parallel with each other.
