And we have also been busy updating everything else to support this:

We tried to support this in F-10 by having a test run with ping. We figured 
that is a simple well defined app that could be used as a test subject. We 
opened bz 455713 to document the change over. Turns out that people compile 
their own kernels and do not necessarily turn this on. So, what do we do in 
that case?

We tried and got turned back. How does rpm work on kernels that do not support 
file capabilities? I'd like to see us get past the initial objections so that 
we can start removing some of the setuid bits.
