Upd.: Since it turned out that there are still user who use it, we'll not remove it! Thanks for the feedback!
Long time ago, on smaller screens, this was a necessity for some users (including me) to enter more text than is visible.
Time goes on and bigger screens gain more and more market place. It seems like it's not that useful anymore and even may lead to confusion to new users.
So, if there's no serious objection, we'll gradually remove them from most of the screens.
