Would go along with all of the above except point 14.
If you tune any ILS when flying a NPA then you will get a check appr guidance message. On FMS2 equipped aircraft selecting the ILS on an NPA will cause the VDEV to be obscured which is inconvenient on a conventional NPA and absolutely forbidden for an RNAV. This 'tune a random ILS' is therefore regarded as bad practice by most and is to be discouraged.
