You're correct about the LazyProperty. The Python port tried to validate some feature before the feature itself existed because the Property class required a valid Feature instance, and would forever mark that Property as a non-erroring sentinel value. The LazyProperty tries to see if the feature has ever been declared and if it does, converts the LazyProperty to a real Property. This is being done to match Jam's functionality.
