I don't get your drift???
BA have hired non type rated in the past and will continue to do so. It fits recruits onto a fleet where it needs people at the time. You might be 737 rated but they could well need 320 so will be offered a new TR unless you want to stay in the hold pool and lose seniority.
Similarly when they hired directly onto longhaul a few years back people weren't exactly walking in the door with 777 or 744 ratings. Again it was a heavy TP or jet rating that got you in the door and in return a new type rating to put onto your licence courtesy of BA.
