I was trying to convey this is a problem with stable releases too. Users
install all sort of 3rd party RPM's and given that RPM's has file deps
the update can't happen. It's naive to think that this is not a problem
with stable releases. Do you disagree?

Here's a question. Do you think the user really cares whether it's done
at the yum level or the PackageKit level? No. So here's the story board

 - User tries to update system
 - Transaction can't happen
 - Some magic in the PacakgeKit yum backend to figure out the biggest
   possible set that actually will make the transaction happen (hint:
   look at a yum plugin that actually does this)
 - User is informed of this by PackageKit showing the update list
   but with some of the packages unchecked (GtkCheckButton)
 - User reviews the checked updates and presses update
 - Life goes on

Uhm, that was actually what I was suggesting with saying the user should
be able to cherry-pick updates.
