Leveraging browser specific implementations is a good thing - but not optimizing your code for other browsers that actually follow standards is bad practice. Microsoft uses an interesting JavaScript implementation to find DOM elements in its Outlook Web Access by their unique ID(s). Interesting in a way that it implements a workaround for other browsers that is not really optimized and therefore a potential performance problem.
