Yes I find that really interesting! It's one of those things (like pieces of code) where: A) You should build often enough that the institutional knowledge and practice can be handed down effectively between generations or B) Not build until it breaks and the people doing it have to rediscover and properly design it again from scratch. It's the dangerous middle ground where people need to modify/rebuild something in the meantime, but lost the practice and knowledge about how to do it properly!
