I agree.
May I propose XDG_DESKTOP ?

Sorry I am late to the party here and may be off thread.  This was discussed back in 2009 with the proposal at that time being XDG_CURRENT_DESKTOP.

The shipping versions of LXDE have been using this to control how the menu processor matches OnlyShowIn and NotShowIn.  It also uses XDG_MENU_PREFIX to control the file lookup on the toplevel ${XDG_MENU_PREFIX}applications.xml
