In Sean Carroll's new book, which I just started reading, he says Many Worlds could be called Austere Quantum Mechanics because it adds nothing to Schrödinger's Equation because nothing more is needed to explain observations. Hugh Everett didn't add any new physics, when he came up with Many Worlds, he just followed the Schrödinger Equation as far as it would go and junked a lot of useless gunk (like the collapse hypothesis) that did nothing except make people who were squeamish about the idea there was more than one version of them more comfortable.
