On both Unity and Plasma, Qt is using the Status Notifier protocol.

So most of the issues you described are actually limitations of either that
protocol or its implementations (indicator-application, Plasma tray), not
bugs in Qt.

Regarding updating the menu when the icon is hidden, it should work fine
on Unity. Can you check if the systray example from qtbase examples works
for you (it has dynamically enabled/disabled Minimize, Maximize, Close

In any case, this is definitely not specific to PyQt, so it should be better
discussed in the Qt bug tracker.
