Before the action center, TrayTip issued only balloon notifications linked to the tray icon. So in case, it did (and still does) make sense that
TrayTip has no effect if the script lacks a tray icon (via #NoTrayIcon or Menu, Tray, NoIcon).
balloon tips have been completely replaced by "toast" notifications in Windows 10, so TrayTip already produces a "toast" notification.

To me, this should mean that #NoTrayIcon should not suppress "toast" notifications in Windows 10. Is that possible to achieve somehow?
