To do this:
System > Preferences > Keyboard Shortcuts
Scroll down to Desktop > Show the panel menu
Assign a new shortcut to that by clicking it, pressing the shortcut you want (Winkey/Super L) and clicking Close.
The idea behind Linux (one of them anyway) is to be able to configure things how you want. Forcing people to have a set use for Super would go against this.
amar is most definitely not the exception. I tend to use super+letter combos for quick app launching. I know others who bind it as meta for emacs as well.
