ILS 119.5. WB's SATCO is alluding to other airspace users who use a regional pressure setting to maneouvre up to say 45 000'. In this instance, when coordinating with said users, finding that the 30' per millibar assumption is wrong has come as quite a shock and no-one is quite sure exactly what to do about it.
As far as the QFE/QNH issue is concerned, I think people are starting to get a little confused. We use QFE in the instrument and visual circuits and for aircraft flying close to, or through, these patterns. Outside this, ac should be flying on a RPS below the TA and the SAS above.
Chilli, aside from the differences of necessity due to mil vs cvi ops, there aren't that many key differences between "your" book and "ours." They would all have come from the same root document in the dark mists of time. But why would you change from QFE to QNH on a missed approach? Maybe yes if you were flying away from the airfield after the approach, staying below the TA, but certainly not if you were going back around for another go.
