Issues #18088, 18089: Introduce importlib.abc.Loader.init_module_attrs() and implement importlib.abc.InspectLoader.load_module(). The importlib.abc.Loader.init_module_attrs() method sets the various attributes on the module being loaded. It is done unconditionally to support reloading. Typically people used importlib.util.module_for_loader, but since that's a decorator there was no way to override it's actions, so init_module_attrs() came into existence to allow for overriding. This is also why module_for_loader is now pending deprecation (having its other use replaced by importlib.util.module_to_load). All of this allowed for importlib.abc.InspectLoader.load_module() to be implemented. At this point you can now implement a loader with nothing more than get_code() (which only requires get_source(); package support requires is_package()). Thanks to init_module_attrs() the implementation of load_module() is basically a context manager containing 2 methods calls, a call to exec(), and a return statement.
