`split` function in `scala.collection.parallel.Task` not public?

I have a scala.collection.parallel question: Why doe the split function in the Task trait have package private visibility? I’m trying to implement the TaskSupport trait and have identified that certain tasks should be split via the shouldSplitFurther function, however, the method to do the actual splitting is not publicly visible :frowning: . Can someone advise? Is this something I should make a ticket about? Thanks!
