I don't have a strong opinion about what to do about this vulnerability,
but I know that none of these three reasons are a good reason to not
change anything. Dictionary key order has never been guaranteed, and
changes from time to time. Any code relying on it is broken to begin
with. This is one of the reasons not to use doctests in the first place:
comparing dicts textually has always been silly.
