This line of reasoning is popular, but it lacks one perspective: people are social animals and many instinctively want to climb hierarchies. If you promote junior software engineers into management based on interest then a lot of junior hires will start manoeuvring for that, instead of trying to get good at their trade and proving themselves that way.
I’ve worked in big companies with the philosophy you’re advocating, and my impression is that they turn very political and lose focus on the day to day engineering work. In the extreme the engineering work even turns into something “dirty” that you should know as little as possible about, because that’s the way to be promoted into higher paying / higher status roles. When 10-20% go around “virtue signaling” their ignorance it quickly destroys the culture.
