It turns out that injecting the keys necessary for incremental tasks causes a significant startup penalty for many larger projects. For example, akka starts up about 3 seconds faster if do not inject these settings for the tasks returning `File` or `Seq[File]`. Given that all of these apis use java.nio.file anyway, it makes sense to not backport them to older tasks.
