From my admittedly limited experience KMM is a complete mess. There doesn't seem to be a reasonable feature set across platforms. Even the standard library has massive holes, forcing you to littler your code with expect/actuals everywhere. This might be manageable for my own code, but completely destroys the ecosystem. A very large number of important libraries only works the JVM. Jetpack Compose and Compose Multiplatform are also not the same. I typically can't use libs written for Jetpack Compose in Compose Multiplatform.
