I noticed, there are sourcegen branch:

<https://github.com/Kotlin/kotlinx.serialization/tree/sourcegen>

. I am curious, is it because plugin isn’t a solution after all?

Plugin API isn’t available on Kotlin/Native compiler yet. Furthermore, experimenting with api is quite slow when you have to precisely manipulate produced bytecode

Is there any chance plugin support will be dropped?

Since the whole library is experimental thing, we are far from making final decisions on it. Compiler plugin is useful thing though, but it can be changed completely (maybe even generate source code)

Make sense. Thanks for info
