Should frozendict be ordered as of Python 3.7?

[w0rp]

Hello! I have a question, and I'm wondering if this is just something that can be clarified prominently in documentation, or if it's something that can be changed in the implementation. As of Python 3.7, dict is ordered by insertion order, and OrderedDict is now redundant. This can be seen in the "What's New" page, and was decreed by Guido: https://docs.python.org/3/whatsnew/3.7.html

Should frozendict also be made to remember the insertion order officially, to match the newer behaviour of dict, if and only if you're using Python 3.7?
