IIRC one of Odersky's stated goal for Scala 3 was to address exactly this issue. That being said, it is developed in a research setting so I guess even if they restrict these features now, there will be new ones added over time...

Scala has always been an opinionated language. The main difference is that this time is holding opinions against itself. Previously, opinions were held against Java, that's why there are features such as case classes, traits, and immutability by default. They answer to Java problems.

Scala is now mature enough that some issues have emerged. Typeclasses are cool, but programming typeclasses in Scala is a bit clunky. The type system is very powerful, but it could be even more powerful and that would actually help people write simpler code. And there are a bunch of unused features that could be removed. This is what Scala 3 is about.
