I've noticed, that new `kotlinx-serialization-runtime-js.js` file for Kotlin/JS is "resistant" to the DCE plugin, even if serialization is not used. It is reduced by DCE from 420KB to 165KB. The old one (0.10.0) is reduced from 374KB to 10KB in the same configuration. This has impact on the size of the output files for Kotlin/JS apps, if the kotlinx.serialization library is present in the sub dependencies, but no serialization features are used. Any idea what is the cause of this behavior? Any chance it can be fixed?

It can and should be fixed.
Could you please file an issue on github? If you will attach the simplest reproducer, it would be awesome
