I see Kotlin as a great choice for these who don't want Java verbosity but can't really get used to read Scala.
The hard truth is that Scala was not designed with tool support in mind and it probably never will be. For example hierarchical implicit conversions, while powerful, are terrible for tooling.
You should pay attention to what's going on in the ecosystem. Dotty comes with LSP support. The Scala Center's main focus is tooling. JetBrains has been pretty committed and cooperating as of late. And several projects are building serious alternatives to SBT.
Because it does a pretty good job with implicits now: https://blog.jetbrains.com/scala/2018/07/25/intellij-scala-p...
Most libraries — SBT is one example — have shifted away from the use of excessive overloading.
