So if it wasn't for dump - that nobody uses any more and that was considered a hack even back when and never supported things like xattrs etc - unix probably wouldn't have a ctime at all (or would have implemented a "creation time" because people would have asked for it). So I'm sure there are reasons for ctime. That just doesn't mean that it's really "good", the same way there were reasons to name "creat()" without the "e".
