BOAC did it for many years with very few incidents until the BEA mafia arrived after they had changed their monitored approach “change hands” style..seem to remember the latter had quite a few incidents. Neither the airmiss with the stationary hotel nor the 777 prang demonstrated that the new BEA procedures were foolproof. (For the latter the captain ordered PF to uncouple from the glideslope which didn’t happen allowing the speed to fall below min drag until stall protection kicked in).
As for approach briefing any professional outfit does it with or without monitored approach.
