Fair comment
"When the traffic circuit is in a right-hand pattern this should be specified. A left-hand pattern need not be specified although it may be advisable to do so if there has been a recent change where the circuit direction is variable"
So when there's no recent change, the last part of the sentence evaporates?
Not fully conversant with ICAO doc but this seems a bit vague. What does "recent change" mean ? Is it when you've been doing left hand circuits & then been given a right hand one ?
Suppose you've had left & right circuits going simultaneously for 30 mins. - who says what & where ?

Is this supposed to be for traffic already in the circuit or does it apply to joiners as well ?
From a personal point of view, I'm happy for the circuit direction to be given in each position report, whatever it is - it's not unknown for joiners to go the wrong way
