I am not sure I would call AFCIs a close cousin to the GFCI (except
that they are both more expensive that a non-xFCI breaker).  They
serve different purposes.  The (arc) faults that AFCIs are designed
to interrupt would commonly be passed through the GFCI without notice.
GFCIs are designed to protect people from shock, and AFCIs are
designed to protect against fire from the arc (which also tends to
protect people, but less directly).
