It seems to incorporate some novel ideas despite its obvious shortcomings. I also think that so far Linux distributions have done very poorly when it came to cross-distribution/forward/backward compatibility of packages. This is a non-issue for popular Opensource packages since they can be easily packaged by the distributors. But not so popular packages sometimes need to be installed in a hacky way when they are not available for the target distribution. Even worse when dealing with commercial software, it can happen that it degrades with each distribution update. Also I think that probably the package format will improve over time and add additional features, that would allow auditing for instance. Also with proper de-duplication (perhaps even on filesystem level) it should be possible to also deal with waste of space.
