I don’t think “hoarding” is a useful framing. Instead, the observation is that granting others access to projects has a time dimension: you need to not only find them trustworthy now, but also reasonably believe that they will remain trustworthy. That last part is much harder, and includes things that are partially outside of the other person’s control (like account takeovers, being targeted by foreign and domestic law enforcement, etc.). I generally think projects should accept more maintainers; however, your point about asymmetry goes both ways.
