Ok. Two RIB entries for Comcast. Your argument doesn't scale.

We're talking about end user assignments made by ISPs, not ISP assignments.
Do the math for how big a chunk Comcast needs, assuming they give
each residential customer a /60, or a /56, or a /48. If their first chunk
was sized based on ubiquitous /56s and it turns out /48 would have been
better, they may need another trip to the well.
