Isn't there a name for this pattern? I swear I remember reading a piece on how having a team member leave can be good for cohesion and efficiency, because everyone is free to vent about old, bad decisions without targeting anyone still at the company. I think it was part of a story about a team clearing their technical debt by convincing a reluctant manager that they needed to undo the last guy's mistakes.
