At what point, and why, did KTS files start needing  to be named `.main.kts` to be recognised for execution? It's a bit of an annoying naming restriction TBH Was it necessary?

Previously any plain `.kts` name could be executed.

did it ever? I only remember third-party tools like kscript supporting that, not Kotlin itself

the subtype is there because scripts can have different definitions

I think the `main` name is to allow calling it with `kotlin foo.main.kts`, without `main`, it was not working, `kotlin foo.kts`

exactly. `main.kts` is one that is provided in the compiler distribution, `gradle.kts` is one provided by Gradle, etc.

Its probable I confused this because of earlier using *kscript*, as you said <@UJQB4DJF7>
