My quick on-vacation response is that attaching more objects to exceptions
is typically viewed as dangerous as it can lead to those objects being kept
alive longer than expected (see the discussions about richer error messages
to see that worry come out for something as simple as attaching the type to
a TypeError).


This isn't an issue for printing arguments or other locals in tracebacks,
though. The traceback printing code can access anything in the frame stack.
