The second part about POSIX file capabilities was realized shortly 
afterwards while thinking of possible other similar cases, and has been 
fixed too now:
http://rpm.org/gitweb?p=rpm.git;a=commitdiff;h=4d172a194addc49851e558ea390d3045894e3230

To my knowledge no distro actually uses the file capability support in RPM 
though.
