You're right. Fullscreen at desktop display mode dosn't change other windows. Remains the benefit of being able to drag the mouse over to the second monitor and for example drag someone into another channel in teamspeak / ventrillo. Many games today like WoW and Anno 2070 (excellent GUI) have such a "desktop mode" and I appreciate it a lot.The needed changes in LWJGL are minimal. I did it myself, but I like the signed AppletLoader.
