Doing devops/sysadmin, I frequently find myself spending 90% of my time on the last 1% of systems that I can't declare out of scope but that are broken/nonconforming for "business reasons". I'd be 10x more productive if I could just turn those off. Every time, I try to make the fixes/write the code that will smooth the next time, but the next thing always arrives before I finish. I've written enough code to recognize the same pattern in any large codebase.
