Comment 4 for bug 753276

For wine users, this is a usability problem, not a spec compliance problem.

The flat concept for finding apps breaks down when installing
Windows apps, which tend to install a handful of app menu items
in a deeply nested group. Often, these include menu items
named 'Readme' or 'Repair' whose names don't make sense without the
hierarchy. (Which of the 75 Readmes wins? Or do they all get icons? Confusing!)

This has bubbled up on the forums, e.g.

This bug means a significant step backwards from treating Wine apps as first class citizens, which is sad.
