That's not quite true. The class decimal.Decimal must obey those standards.
We could easily add decimal32/64/128 types to the module for those
different objects (and I think we probably should).

For that matter, it wouldn't violate the standards to add
decimal.PythonDecimal with some other behaviors. But I can't really think
of any desirable behaviors that are mathematically possible to put there.
There isn't going to be a decimal.NeverSurprisingDecimal class in there.
