Guidelines change:
http://fedoraproject.org/wiki/Packaging/Guidelines
The following addendum was made to the FileAndDirectoryOwnership section:
Another exception for directory ownership in packages is when there is no clear dependency hierarchy.
An example:
Foo-Animal-Emu puts files into /usr/share/Foo/Animal/Emu Foo-Animal-Llama puts files into /usr/share/Foo/Animal/Llama
Neither package depends on the other one. Neither package depends on any other package which owns the /usr/share/Foo/Animal/ directory. In this case, each package must own the /usr/share/Foo/Animal/ directory.
