Micropython' s Damien George got back to me and indicated that once they get around to working on Python 3.6 compatibility (they're currently still working on 3.5), they'd likely also need to go down the path of using collections.OrderedDict in the situations where the 3.6 language spec calls for it (MicroPython's default dict implementation is less sparse than the CPython one, trading greater memory usage efficiency for an increased risk of hash collisions, so it's unlikely the new implementation would count as "compact" from that perspective).
