The Windows tray was never ment to store pointless menus, but there was a documented API and programmers started using it because it was convenient. Same situation here.
As a side story, a friend sent me a VMWare image, but I run VirtualBox. Instead of converting the thing, I installed the trial version of VMWare Fusion on my Mac. Version 3 apparently has a menulette to access your VMs applications directly. After the trial expired I no longer have the option to remove the menulette, without uninstalling VMWare entirely. It used to be the case that a simple alt(option) click and drag would poof the icon away. More developers are failing to implement these "conveniences" properly.
