All Java interfaces should receive an Any parent

[scabug]

...and a necessary step to be taken in combination with this is that 'eq' be defined on Any. All the details of why this should be done, including an almost unprecedented level of agreement, can be found in this thread: https://groups.google.com/d/msg/scala-internals/jsVlJI4H5OQ/BwdZT5hpKtsJ

Agree, but we need to keep in mind that interfaces can have implementations since Java 8.

Fortunately that's irrelevant, since they still cannot have state.

would need a SIP; out of scope for Scala 2

even in Scala 3, value classes are kind of in a half-dead, half-alive state where they're in the language, but not typically recommended for use (unless you're realllllly sure), particular since Scala 3 has opaque types. but they're not deprecated either because we keep waiting to see how Project Valhalla to turn out

in any case, further discussion if any should go on a new thread in https://contributors.scala-lang.org, let's not resurrect this ticket as a discussion site
