I will update this question taking into account the new patch and 
inability for desktop-specific list to add/remove apps.

$XDG_CONFIG_HOME desktop-specific list:
      [Default Applications]
      foo/bar=app2.desktop

$XDG_CONFIG_HOME list:
      [Added Associations]
      foo/bar=app2.desktop
      [Removed Associations]
      foo/bar=app4.desktop

$XDG_DATA_HOME applications:
      app5.desktop

$XDG_CONFIG_DIRS list:
      [Removed Associations]
      foo/bar=app2.desktop

$XDG_DATA_DIRS desktop-specific list:
      [Default Applications]
      foo/bar=app3.desktop

$XDG_DATA_DIRS list:
      [Default Applications]
      foo/bar=app1.desktop
      [Added Associations]
      foo/bar=app4.desktop

$XDG_DATA_DIRS applications:
      app1.desktop;app2.desktop;app3.desktop


Please show how to iterate through the list.
Is the result app2.desktop;app3.desktop;app1.desktop;app5.desktop?
