Process (agile or not) always has three goals: legibility, scalability, and fungibility. Both management and devs alike can be concerned about the bus factor, which falls under fungibility. Of course, an organization can have (or lack) humanity beyond those three goals. And hire people who have (or lack) the requisite humanity to bring to their role. If someone treats the bus factor or general fungibility casually, that's a problem.
