#### Bug, feature request, or proposal: Request #### What is the expected behavior? `.mat-input-invalid` class should be added to empty required fields on pristine. #### What is the current behavior? `.mat-input-invalid` is added only if the field has validator and has been touched. #### What is the use-case or motivation for changing an existing behavior? Empty mandatory fields should be visible at first sight. #### Which versions of Angular, Material, OS, browsers are affected? Angular 4.0.1 Material2 Beta 3 #### Is there anything else we should know? I love you. ;)
