You mean something, that won't allow two packages to own the same file? Something, like, rpm or apt?
No, not really.
For one thing, package managers are only useful on packages supplied by the distro (or otherwise bundled using that convention), and we need something that allows for installing (and uninstalling, and backing up configurations for, and...) software safely and systematically in the general case.
For another thing, even packages installed with a distro's own package manager can typically dump whatever files they want wherever they want, rather than having the OS restrict them to a controlled environment.
