When all compiler APIs become stable (FIR and so on), Kotlin Gradle Serialization plugin would be outside the Kotlin repo and having its own version?

Serialization libraries are under kotlinx repo with its own version, I would expect that in the future for the plugin too

The serialization plugin already is versioned separately, isn't it?

no, <https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-serialization/build.gradle.kts|https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-serialization/build.gradle.kts>

I think they are doing it so because the compiler APIs are changing continuously so you need to use an specific version of KGP to get serialization plugin working.

I got a curious issue related to that as a plugin I have is using compileOnly for KGP but implementation for Serialization plugin, so the PR for 1.7.20 was exploding because I was only overriding KGP in the consumer library and serialization was still using 1.7.10
