Right. Ordered by default is a very serious implementation constraint. It's only superior in a sense that it completely subsumes/obsoletes PEP 520.
Just to be clear, PEP 520 is more than just OrderedDict-by-default. In fact, the key point is preserving the definition order, which the PEP now reflects better. Raymond's compact dict would only provide the ordered-by-default part and does nothing to persist the definition order like the PEP specifies.
