Well, no, that's not sufficient on its own either. But yes, it's a
stronger argument.

Having it *do the wrong thing* one run in ten is even worse.

If you need chardet, then get approval for the third-party component.
That's a political issue, not a technical one. "This needs to be in
the stdlib because I'm not allowed to install anything else"? I hope
not. Also, a PyPI package is free to update independently of the
Python version schedule. The stdlib is bound.
