I believe all RIRs charge by size for LIRs in some form or other. ARIN is by max_fee(IPv4,IPv6). 

In the case in question (COMCAST), they are already in the maximum fee category, so expanding their v6 allocation to /12 would not increase their fees. 

I would argue that since (at least in ARIN), you get 16x as much address space for 2x the fee, revenues from the expanded customer base should easily dwarf the cost of additional addresses to issue proper /48s to every customer.

I think COMCAST intends to continue subjugating their customers with limited address blocks for the foreseeable future. 

I am hoping that other IPSs will be more rational and eventually market pressure will bring about ubiquitous /48s.
