I think the DStream API does expose calls which basically call foreachRDD,
like the map etc. But from an app developer point of view, it makes my
application much cleaner if I do something like {{dstream.map(_.getValue)}}
than having a foreachRDD call for every transformation. I don't even see a
major maintenance issue as far as the codebase is concerned, since the DStream
API mostly just use public API. Really, removing these methods will just make
streaming apps more complex.
