and a 737 captain now
Obviously the problem here, a "big" aeroplane pilot who only knows how to fly that way, like a few other experienced instructors here I also fly big aeroplanes - bigger than a 737, but I still do not teach flying the VASIS, not only is it a very shallow angle, but puts you FAR further into the field than needed, in the States not a big problem, but certainly in the UK there are many fields where teaching people to land like this results in them using up more airfield than is comfortable when they land other than a big airfield that has approach lights, especially in light winds, and the cause of more than a few crashes. I would agree that powered approaches are the norm these days, but as many have said, not 3 degrees.
