To prepare for Java 9+ modularization, the standard library should not contain classes in scala.reflect

[smarter]

Java modules do not allow split packages, that is having two modules on your modulepath containing packages with the same name (note that packages are not hierarchical in Java, so scala and scala.reflect are unrelated packages).
Unfortunately, the standard library contains a few classes in scala.reflect: https://github.com/scala/scala/tree/2.13.x/src/library/scala/reflect So we need to find a new home for them. Everything but ClassTag is basically obsolete (although my attempt at getting rid of them wasn't successful). So the main question is: where do we put ClassTag ? I think it's harmless enough that we could just put it in scala directly. WDYT ?

I had the same concern, but there's nothing in the scala.reflect package in scala-reflect so there's no split package: https://github.com/scala/scala/tree/2.13.x/src/reflect/scala/reflect

I'm not sure if it was intentional or not, and also it's a little confusing, but it looks like we dodged this particular bullet.
