Its more about being a servant leader and not a bottleneck than literally being "not needed". Its a mindset of wanting your team to be able to operate without having to check with you (the EM) on every little thing. I've also heard it called having IC's be a "manager of one" where they can independently work on things, get work finished, etc. without needing constant nagging.

A good manager I had once had the approach of setting guidelines and "just getting out of the way" and I try to follow that, it works well for most people.

I like being a servant leader. In no way does that mean I can go on holiday and people won't miss me. They will miss my services. If people don't miss me, then they must HATE me as a manager.
