That feature is a poor man's session management for applications that do not implement any specific session management features. It badly interferes with proper session management support, so applications must be able to disable it. This enables fixing applications with QGuiApplication::quitOnLastWindowClosed() true - the default - dying too early, before they are enumerated for the list of applications to restart on session restore, thus preventing them from being restored. See https://bugs.kde.org/show_bug.cgi?id=354724 [ChangeLog][QtGui] Qt asking to close windows on session exit as a fallback session management mechanism has been made optional. Disabling it fixes session management for applications that implement full session management. See QGuiApplication::isFallbackSessionManagementEnabled().
