It's not something I expected, and the warnings around traceback objects are a good indication that other developers have not expected it either. One poster on python-ideas said "Working with traceback objects can easily introduce hidden circular references, so it usually better not access them at all".  Since these 'hidden' references are not used in many cases, it is surprising that they would be required.

I have, and it has been so far.

When does Twisted want to manually create traceback objects? Failure has specific functions to stringify the traceback to remove the references mentioned here. Creating a fake traceback would be one way to achieve that, but if the references did not exist I'm not sure what the goal would be.
