So goalpost moved from “libraries can solve visibility problem with package level visibility” to “libraries should not try to solve the visibility problem because it is not even a problem at all”?
No, it has not. If you are software engineer you should understand the difference between what I actually said and what you quote from logical perspective. I said "many libraries", not "all". For majority of use cases package level visibility is sufficient and is more granular. Yes, many libraries have already migrated and include module-info, but they still are fully compatible with classpath and actively use more classic mechanisms for visibility control. How many projects do use modules? I haven't seen a single one yet.
