You are correct here. It was previously the case that we did not create the default IME window until it was requested. That changed and so now it is useless and can be removed.

I would be curious about this. What was your app and could I test it? I find there are many applications that are half-ime aware. That use ImmIsUIMessage with a NULL hwnd and expect the message to be processed but the default IME window. So we need that behavior to remain true.
I would be curious why your app was unhappy about that.
