I'm puzzled though that you think that CAP 413 suggests addind 'traffic' to the airfield name - I read it as a procedure that is applied if one chooses to use Safetycom.
If you look at your post of 22.06hrs yesterday you will see that it was you who made this suggestion................
The suffix 'traffic' is used when at an aerodrome which normally has Radio but it might not be operational at that specific time: unmanned due to no staff, gone for a pee etc).
In these circumstances safetycom
must not be used, rather '(station name) traffic'.
It follows therefore that at a field which has no dedicated radio the term '(airfield name) traffic' if used at the beginning and the end of the transmission on Safetycom (and within the altitude and distance ranges given in the official Safetycom document) IMHO would maximise situational awareness of other traffic in exactly the same way as traffic awareness is brought to normally manned but temp unmanned airfields with their own dedicated frequency: the addition of 'traffic' highlights that a response from the ground is unlikely.
