I'm glad this is finally out, and the most important part is not that it's a very distant dwarf planet (though that is very cool), but rather that its existence in that orbit completely blows a hole in the Batygin & Brown "Planet 9" hypothesis. So, there almost certainly isn't a hidden distant giant planet in our Solar System.
(Which quite a few of us, including @sundogplanets and myself, have argued was the case for years, but this rather confirms it)
