There's definitely a middle ground between archivist and reckless bringer of breaking changes. In most cases it doesn't even require much extra work to maintain, the people in charge just don't care at all, or have the same attitude of just let someone else do it.
Kind of reminds me of the old meme with home submission laying on the Nike logo like it's a hammock, with text saying, "can't someone else do it?" [1]
Archiving is for archivists, and luckily, the web has some. If you don't want to be one, you can't tie yourself to the past.
