Most people don't have the luxury of picking and choosing exactly what they work on. I don't WANT to work on keeping some legacy tooling from falling apart, and I would consider maintaining it a chore. That doesn't mean that it can just be abandoned though, so my boss will tell me (or someone else) to go work on it when needed and that's a perfectly normal and acceptable thing to happen in a workplace.
