What about dual-homed customers? Or are they all expected to have their own
PI space?

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.
