I would say one partial cure for this is to contribute to open source or if you are using open source in your projects see if you can get your company to allow you to contribute any fixes you have implemented up stream. Although at times rather than asking, I have fixed issues in a cpl of hours after work and pushed these up. But the simple fact is everything, even the most "advanced" projects eventually become obsolete, so I wouldn't worry about it, it is just part of working in tech.
