It's not as clear-cut as it looks in C#. Although refactoring the
class in this way doesn't change the API, it does break ABI, which is
significant in an environment where virtually everything is
distributed in binary form. This happens because a property access
compiled to CIL byte code is transformed into a call to a getter or
setter method, which is a distinct operation from an ordinary
attribute access. Whereas in Python, an attribute access is just
compiled as an attribute access no matter what the underlying
implementation of that access may end up being at run-time.
