Thinking about it a bit further, I suspect implicit normalisation of chained exceptions could cause problems when we only want to set __cause__ without setting __context__ (e.g. codec exception chaining). I'm going to ponder this one for a while, but happy to hear anyone else's feedback. At the very least, I think the C API docs could use a bit more clarity on the intricacies of C level exception chaining.
