I know Paul Sokolovsky does not claim to speak for MicroPython, but I think he had better shut up or he's nevertheless going to damage its reputation beyond repair. I note that micropython.org claims "MicroPython aims to be as compatible with normal Python as possible to
allow you to transfer code with ease from the desktop to a microcontroller
or embedded system." To me this implies that it is entirely up to the MicroPython project to decide what they'll do about the order of dict elements -- they can keep doing what they are doing, or choose a new dict implementation that satisfies their space and performance needs while also preserving order, or give developer a compile-time choice, or give users a choice at startup time, or something else I haven't thought of yet. Any of those options is better than continuing the flamewar that Paul is waging.
Finally: the dict type should not be endowed with other parts of the OrderedDict API, not should other API changes to dict be considered.
