That’s a very good point. THE QNH value shall not be announced even though not very clearly written in the FCOM to avoid confirmation bias; Most importantly the destination QNH should be preselected in the ISIS at least in case ATC gives you a wrong QNH (eg 1011 ISO of 1001) like it happened before and almost caused a fatal accident in Paris where an A320 went as low as 6 feet from the ground during go around.
