I don't see the point. People who want Jupyter or an IDE know where to find it. Other people who want the basic REPL and mostly use editors anyway are annoyed.
Well, perhaps the usual suspects can get another infoworld self-promotion article out of it.
If Python is going to include a REPL (which I think it should), it might as well include useful features that people expect from a modern REPL. (That being said, I personally always install ipython...)
