I completely agree with this.
I mean, Queen Mary and Queen Alexandra were both Queen Mother, but it wasn’t used. With QEQM it was used to distinguish between her and her daughter.
This is exactly the same.
If when QEII died the BBC had announced that “King Charles will return to London accompanied by the Queen” people would have assumed they were talking about his mother’s body.
Once people get used to the fact that HM The Queen = Camilla the consort bit will drop from use.
