The way I'd got for it making

Applet::immutable() {
    return property("immutable").value<>()
}

then we change our Q_PROPERTY in Plasma::Applet to go to a real
implementation

system tray containment can then also implements the property.

Another possible technique is we export a new class which inherts Applet,
contains the virtual but doesn't contain any member variables.
Then in Applet we can static_cast<AppletExtension>(this)->myVirtualMethod();

If we want the system tray to have any more special cases, that's not as
crazy as it first sounds.
