I think it's a positive development and a sign that GUI applications are now being treated seriously. There's just no way that any generic widget set is going to 100% fill the needs of an easy-to-use, complicated GUI application.

Cobbling together a GUI with a limited set of cookie-cutter widgets that are difficult to modify is no longer acceptable.
