Because the parallel collections no longer inherit from the regular collections, they don't inherit any documentation from them, which means that most methods (map, groupBy, ...) have zero documentation in the generated scaladoc (e.g.: https://www.javadoc.io/static/org.scala-lang.modules/scala-parallel-collections_2.13/0.2.0/scala/collection/parallel/ParSeq.html#groupBy[K](f:T=%3EK):scala.collection.parallel.immutable.ParMap[K,Repr]).
