The referenced tracker entry proposes, "Issue31265:  Remove doubly-linked list from C OrderedDict".  I don't think that should go forward regardless of whether regular dict order is guaranteed.

Inada presented a compound proposition: either guarantee regular dict order or let him rip out the core design of OrderedDicts against my wishes.
