Your proposal doesn't really sound like it deprecates files, but rather that it enhances them with attributes. Most operating systems other than Unix have already expanded on the file as a bag of bytes to one that supports features such as extended attributes and forks. Even most contemporary Unix file systems have xattrs (most notably XFS), but overall they seem to have had limited impact, and in the case of NTFS-style alternate data streams, even introduced some nasty security risks. Really, what you seem to want is a file system with built-in version control and network sharing? Git and Mercurial are already virtual file systems of sorts, I guess.
