Because Kotlin took a dumb turn about 5 years ago and decided that multiplatform was their future instead of the jvm (because they felt threatened by React Native and Flutter on Android). Point being, they don't want to tie themselves to the jvm anymore. The language has been stagnant for years as they've had to reimplement tons of java libraries and also shoehorn the extreme complications of multiplatform into the awful gradle build system. All for this dumb dream that has gone no where.
