I get that. But in practice, it hasn't been a problem. For files I consider critical and difficult to replace, I use SnapRAID or par2, and others are either used frequently and I would notice the corruption, or replacing them wouldn't be a problem. Using a smart filesystem would be an improvement, but it comes at the expense of less flexibility and more complexity, and, until recently on Linux at least, relying on unstable software.
