Circular dependencies in RPM

I know I have probably been hiding under a Rock but can anyone help me understand Fedora's stance on circular dependencies within RPMs? At least in the past I think circular dependencies have been kept to a minimum as it can cause issues with rpm sorting: i.e. for two rpms A,B with a circular dependency, in different transactions sometimes A goes before B and sometimes B goes before A. In Fedora 20 just running rpm against the 1500 or so packages I have installed on my Desktop I notice that there are 47 sets of "Strongly Connected Components"; basically 47 cases of a circular dependency. Was there a point where this became more popular. I don't remember there being more than a few circular deps for EL6 era rpms. Thanks, Dusty
