Edward's response nailed this one on the head. It has to do with the additional support/hardware required to support a BGP session. Granted, once a BGP session is established it rarely requires any tweaking, but I've spent hours troubleshooting a downed BGP session because the client's IPS signature update decided TCP/179 was malicious.
You also have to implement additional filters to protect yourself from what your client can advertise. I'm lucky enough to work for a major ISP with pretty sophisticated filters built off the public route registry, but not all ISPs have this functionality.
