My understanding is that the helpers do the "80%" solution for you -- pave the cowpaths -- but expect you to do the edge cases yourself, since you know what you are doing and what you want. Too much "magic" breeds a complacent user that expects everything to just work, all the time, which is unreasonable for the simple fact that software cannot read minds.
