Sometimes I think it would have been cool to have gotten into supporting something really obscure like that at an early stage in my career. A near-guaranteed contract renewal as long as the system wasn't replaced. If it was to be replaced, you'd likely have a good amount of warning. You'd be one of a very small handful of people in the world able to support and maintain the system. You could become a deeply knowledgeable expert about the system over dozens of years likely without having to learn a new language, framework or system more than a few times in your career. Of course, the downsides are huge, especially if you limited yourself to that one system. If the contract didn't renew, finding a new job would likely be incredibly difficult. I could see it getting mind-numbingly boring, I guess that might be a plus for some people, but would likely drive me crazy.
