So, I don't think this is a generational thing. I think most people of all ages and generations have mostly just not thought about this. But the reason more people are thinking about it now is that the distribution model has changed on a way that has highlighted an existential weakness with this model.
I lack data, so I cannot say anything broadly. But in the devs that I know, this is 100% a generational thing. It may be different in different circles.
