UI noConflict compatibility

$ grep "})($);" *.js

ui.draggable.js:})($);

ui.droppable.js:})($);

ui.magnifier.js:})($);

ui.mouse.js: })($);

ui.resizable.js:})($);

ui.shadow.js:})($);

ui.slider.js:})($);

ui.sortable.js: })($);

Shouldnt all plugins end with })(jQuery); so we can use them with noConflict?
