            # IMPORTANT:
            #   - `CanHaveMethodSteps` is disabled in the Standard config since it causes race conditions in combination with `CanHaveStubbedResult`.
            #   - It will be reenabled after the introduction of thread-safety specs.
            #   - Do not use it in production yet.
