I'm also strongly against using `from None`. When I'm debugging, I'm like a man who got lost in the desert and is about to die of thirst. Any possible insight into what happened is like an oasis, even if there are just a few drops of water there.

Also, some tools like Django and Sentry show you all the local variables for your stacktraces, which is a godsend. These often have important information that sheds light on what went wrong, and if you remove the traceback they'll be gone.
