Ubuntu user here. I am a bit wary of this change because it breaks the visual consistency from a desktop POV. In theory this idea is great if people used the same icons and conventions. Sadly consistency is not one of linux'es strong points. I fully expect java, tk, qt, gnome, wxwidgets to each design their own window decorators which behave / appear ever so different. Perhaps it would have been better to expose some inbuilt "Windicators" via a DBus service and applications that wanted to show a windicator could set a message to the DBUS service. To be fair maybe the Ubuntu folks have a perfect design for this, but since they havent released it its hard to be optimistic. edit to add more pessimism - This will only make life more difficult for tiling window managers like ratpoison, xmonad, awesome that dont support window decorators, because many apps will go ahead and just assume the presence of a window decorator on every window.
