FWIW dpkg can express this kind of dependency, eg:
Depends: exim | mail-transport-agent
[from: http://www.debian.org/doc/debian-policy/ch-relationships.html]
If implemented, this would have implications for Fedora. You could
have two people who have installed the same package, with a very
different set of dependent packages, leading to some sort of
combinatorial explosion of QA.
