This is just trying too hard. "Servant Leadership" is a buzzword invented to divert the general opinion from the power mechanics that hierarchical organizations are funded upon, i.e., the boss (sorry, leader) commands and the direct reports execute. Being "servant" basically just means being a decent human being, as per putting people in the right condition to carry out their duties, not coming up with unrealistic expectations, and do the required 1:1 coaching/mentoring for career development.

Hand-helding employees as this "blocker removal" interpretation of servant leadership seems to imply is just the pathway to micromanagement. It's ok to shield your juniors from the confusing world of corporate politics, but if your direct reports need you to do a lot of the sanitization/maturation of work items and requirements then why should you even trust their outputs? At that point you're basically just using them as you would prompt an AI agent, double- and triple-checking everything they do, checking-in 3 times a day, etc.

This "transparent" leadership is the servant leadership, or what it's intended to be anyway in an ideal world. Some elements of it are easily applicable, like the whole coaching/connecting/teaching, but they also are the least measurable in terms of impact. The "making yourself redundant", i.e., by avoiding being the bottleneck middle-man without whose approval/scrutiny nothing can get done is fantasy for flat organizations or magical rainbowland companies where ICs and managers are on the exact same salary scale. And it will continue to be as long as corporate success (and career-growth opportunities) is generally measured as a factor of number of reports / size of org. managed.
