Is there any way of softdependencies supported by yum? Is this planned for the 
the future, for plugin basd apps it would be nice to be able to hint to the end 
user that certain optional plugins (with perhaps some hefty deps) would be good 
to install, then in beginning user mode (== default) yum could treat these as 
harddeps, and more advanced users could reconfigure the behavior to for example 
ask the user, or just not install soft-deps.
