I agree with all of that. I try my best to discourage students from opting for film because of the cool factor. Day-to-day, I encourage them to use digital cameras. They've got enough financial problems to contend with, without having to find the money for film, processing, etc. But some of them will not be dissuaded. They wrap it up in talk of the aesthetic, but it's because it's better for your Instagram profile to be seen using a crusty old Pentax 67 loaded with Portra 400 than using a nice new Fuji GFX. I'd challenge any one of them to tell the difference between images taken on those two.
That said, there are students who come here with good reasons to shoot film, and I bend over backwards for them. I had one recently who is using a Mamiya Press Universal. I asked him why, when it's such a P.I.T.A camera. His response: he gets better responses from people he wants to photograph. He gets into conversations with passers-by about his janky-looking camera, and sometimes he gets decent portraits out of it.
Another told me that he gets better photos of skaters at his park, because carrying a medium format camera they think he must be a "proper" photographer, and not just one of their mates with a DSLR and a fisheye. He gets more cooperation, and so gets interesting images.
I guess what I learned from that is that the cool factor of a film camera can be useful beyond simply being cool.
