Yes, certainly not internally, unless re-raising all or selected exceptions,
but as an outside wrapper to a whole app, why not? (You could make traceback
printing depend on __debug__ or some other option if desired).
You could also detect and eliminate redundant repetition in a traceback print
of a recursion limit exception. (I think that would be a nice default, BTW).
