Are there plans for a @Keep annotation for Kotlin/JS projects that automatically whitelists things from being DCEed? Similar to how Android has @Keep for ProGuard?

Is this what you mean? https://kotlinlang.org/docs/reference/javascript-dce.html#configuring

So right now, you need to go into build.gradle and explicitly configure runDceKotlinJs.keep manually for every declaration you want to keep. Whenever you add a new method/field/whatever in Kotlin/JS, if you want to force DCE to keep it, you need to manually update the declaration in Gradle.

What I'm hoping for is an annotation that you can apply to any such declaration in actual Kotlin source (.kt files) to have the same effect. This way, as you rename/move/refactor/delete declarations, you don't need to manually muck around in build.gradle to keep your runDceKotlinJs.keep declaration up-to-date with your actual code.

@ankushg please file an issue

👍 Just wanted to make sure that wasn't something that already existed, or was out of scope for the JB team to work on
