Code Review

This pull request updates the EventQueue class to serve as a producer-side interface and deprecates its direct instantiation by adding a DeprecationWarning in the __new__ method. A review comment points out that because EventQueue is an abstract base class with abstract methods, the redirection logic in __new__ is currently unreachable as the interpreter will raise a TypeError before the method executes. The reviewer suggests removing the @abstractmethod decorators and using NotImplementedError instead to allow the backward compatibility logic to function as intended.
