In order to bring Doraemon to a new generation, save kids from dealing with years of backstory, and to let the voice actors retire from having voiced the same characters for over a couple decades, a new Doraemon anime was created and broadcast in 2005. By this point, censorship standards had gotten a lot more strict in the new era of anime, as what was acceptable for children years ago is not acceptable anymore. This is the reason Dragon Ball Super does not have much gore in it, as opposed to the earlier series. Even the 1989 and 90's anime Dragon Ball Z was censored comparatively in its recut in the late 2000's, Dragon Ball Kai. They're the same series, essentially, but Kai is allowed to do less than Z can despite the target age group not having changed a bit. (This does not apply to the English Dub of Kai, which is often more adult than the original Z dub.)
Still, Doraemon tried to find its way, and so tested the waters, so to speak, with an adaptation of the portable pool story, with the same ending; the boys stumble across Shizuka's bathwater. And in the end, Shizuka shows a bit of her back, and some of her side; not as much as she used to, but still quite a bit.
