Original developer intent doesn't seem relevant. The fact remains that it
has this effect,
and demonstrably makes IPython a better, friendlier tool for learning
disabling it by default will make IPython better behaved in edge cases, but
and less helpful for learning Python.
I'm not saying we shouldn't make the change, just pointing out that there
is a real class of users actively hurt by it.
