Not going to happen.

And then we have the directory style used by all RPM-based distributions:
which, again, introduces yet another problem because not all RPM-based distributions have adopted the /usr merge, which moves /bin/, /lib and /lib64 into /usr
Until all distributions can agree on a single standard heirarchy for their filesystem, there's no chance in hell a unified packaging format will happen, You'd end up seeing distribution-specific .uvp packages being made just to cater to each distribution's file heirarchy's idiosyncrasies, which totally defeats the purpose of a standard package format.
