Tech debt filled mud balls where feature after feature is clumped on top of one another without worrying what came before it and what will come after it are not great to maintain. Sure if you don't plan on maintaining or building on the component and you don't care if it restarts, then let it restart forever. But if it's a component that you plan on adding features to for a long period of time and stability issues are ignored, those types of issues can compound over time and make it more difficult to reason about and maintain.
