Yet most of kotlin standard library is still functions extensions to Java package classes (jvm), if you filter out the function listing in the kotlin website to only implementations common across targets (Common tag), there is very little to be usable.

Due to the nature of being a frontend-for-everything I think it's best to keep the stdlib's platform-specific functionality minimal.

Other platforms don't include Java's standard library, so it would be presumptuous to build one for each platform.
