I have a feeling that mypy might flag circular imports. I've not used mypy myself, but I just saw the output from a project where we enabled very basic use of mypy (no type hints at all, yet) and saw an error reported about a circular import. So with suitable configuration, mypy could help here (and may lead to other benefits if you want to use more of its capabilities). OTOH, having the interpreter itself flag that it had got stuck in an import loop with an explicit message explaining the problem sounds like a reasonable idea.
