it was a suggestion by me to introduce a new type. The problem is that we mixed up notification and osd. That is I implemented support for notification and thought that would be for notification, but it got used for OSD.

Now the initial idea on why I wanted to have it with a dedicated type still holds: having more information in KWin about the window type. That's a good thing in general. So even if it were just an override redirect it should have a type to indicate it's type. We will need that on Wayland anyway that windows must provide more information than currently (no override redirect there).

Concerning the games which use override-redirect: I don't think we should design our API around the brokeness of games.
