Explicit API should also warn about implicit constructors being public.
For example I often use factory methods for classes and sometimes forget to make the constructors of these classes internal, which is unexpected API surface.

I think you can request the feature on kotl.in/issue with that use case.

We discussed it when were designing explicit API mode and decided against requiring explicit visibility for primary constructors: https://github.com/Kotlin/KEEP/blob/master/proposals/explicit-api-mode.md#inspection-exclusions

Also some good reasons in there, thanks 🤔
