Hmm, I wonder if the UX problem with the current chaining might be solved in a different way, by doing something similar to what we did for codec exceptions (where we want to try to mention the codec name, but also don't want to change the exception type, and want to include the original exception text in the wrapper's message).

The codecs related call is at https://github.com/python/cpython/blob/0c1c4563a65ac451021d927058e4f25013934eb2/Python/codecs.c#L389 but most of the heavy lifting has since been refactored out into the _PyErr_TrySetFromCause helper function: https://github.com/python/cpython/blob/55edd0c185ad2d895b5d73e47d67049bc156b654/Objects/exceptions.c#L2713
