great idea! was one of the rationales for A, B, and C. oops.
Now Randy, a young-un like you mightn't remember back that far, but I seem to remember from the time that the primary motivation for ditching classful addressing was due to number depletion, an issue that we don't have in ipv6, and are unlikely to see in the medium to long term. Besides, ipv6 doesn't implement classful addressing; it simply allows LIRs and PI end-users a sufficiently large amount of address space that additional allocations/assignments shouldn't be necessary to even remotely the same extent as in ipv4.
