Junior roles, not junior developers. They're useful for exactly the gruntwork you're describing, freeing up seniors for the higher-level or more difficult stuff while learning from it.
The theory is the roles would disappear because now the seniors can just send AI agents off to do the gruntwork instead of having to hire juniors or spend time on it themselves. It doesn't take into account if everyone does this then no one is training new seniors.
