> So you and OP believe that, these systems are good indicators of skills, so much that the last statement sounds normal?

I do. I think it's good not to box people in, where certain work is only for (my company's equivalent of) L63s and an L60 isn't even allowed to try. But when I do see L60s try, they usually need someone to come by and intervene, because there are critical skills that come with seniority that they don't yet have.

To be more concrete, one thing I often notice in junior engineers I mentor is that they're very "task brained". They understand their job to be nothing more than a sequence of development tasks, so they struggle to understand what's happening or how to help when it comes time for important things that aren't tasks. One guy I knew was frustrated that he didn't understand how priorities are set, and yet would never read the customer stories in his email that the company used to set priorities.
