Default categories for shortcut

Hi All.

When I install my application in linux MenuGroup is created and all  
shortcut's also. But
All of them also appear under Development MenuGroup.
Quick look in .desktop file revealed Categories=Application;Development.
Why Development is in there ?

I found :
data.Categories = shortcutSpec.getAttribute(
                    SPEC_CATEGORIES, "Application;Development");
in ShortCutPanel.java:978

So default categories are Application and Development. I am just  
interested why it is so ? I think development should be taken away  
from the default value and if it is possible to configure categories  
from shortcutSpec.xml it would be nice to have it in Documentation.
