If you have good trust and communication within a team, the scenarios you describe are surmountable. Every strength is a weakness, and every weakness is a strength. IME, heroes are no more a red flag than pretending that good engineers are interchangeable. It depends on the context. The expected outcomes of these teams are different, and that’s OK. If you’re a very small company and don’t have a couple heroes, you won’t build anything important. If you’re a very big company, the heroes that built it left years ago, and you need resiliency more than new heroes (unless the business is going sideways and needs saving).
