IMHO there should be a much larger window between providing an new 
feature in RPM, and requiring it for development. eg, new features
should go into RPM in rawhide & F11 at least 2-3 months before we 
require them. Yes this would have required XZ support to be merged 
much sooner in the F12 schedule, or alternatively merge XZ support
in F12, but don't use it till F13.
