No, not a feature or a bug... it would be a bug to assume the elements will be in order, or to assume the elements will not be in order. It is a happenstance if they are. Maybe for that implementation of the Python runtime that happenstance is consistent, but on another it may not be. My guess (totally a guess) would be for small sets it is expected to be faster to use an array with a linear search than a tree with fewer operations per search, so the implementation starts with an array until the set gets big enough to justify using a tree, then it switches over.
