Such a class could exist, but the stdlib doesn't happen to provide
one as far as I know.

Note, though, that you're relying on implementation details of
OrderedDict when you use it to "fix" your problem in this way.
It happens to work in some versions of Python, but it might not
work in the next one.

It doesn't, but the differences you're talking about are differences
between undocumented behavour of dict and undocumented behaviour
of OrderedDict. The docs are under no obligation to tell you about any
of that.
