... because most Service Provider designs use IGP to address next-hop reachability issues and convergence and BGP solely to transport reachability information (which IP prefix is reachable through which next-hop). And, lacking the infinite development resources, Cisco (and all other vendors) usually implement what people that buy lots of boxes use in their networks (that's why the IS-IS implementation is so good). BTW, even the more "traditional" fast convergence techniques (internal BGP fast fallover) might be too aggressive and do more harm than good.
