(Note: This is already the case. https://docs.python.org/3/library/collections.html#collections.OrderedDict """ Equality tests between OrderedDict objects are order-sensitive and are implemented as list(od1.items())==list(od2.items()). Equality tests between OrderedDict objects and other Mapping objects are order-insensitive like regular dictionaries. This allows OrderedDict objects to be substituted anywhere a regular dictionary is used. """
So you're asking whether to deprecate this behavior?)

So I think that not using the __eq__ method of the keys or values is wrong (dicts do use it), but there's a philosophical question: if two OrderedDicts have the same key/value pairs in a different order, should they be considered equal or not? (Only when we've answered this can we answer the question about keys/values/items).
I'm not a frequent user of OrderedDict, so I don't have a good intuition, unfortunately.
