Yes, IPv6 provide much more address space but if this address space will be wastefully allocated as IPv4, history will repeat itself
This is just a statement of the bleedin' obvious Andrey. However you don't seem to have any data that shows how current IPv6 allocation policies could repeat those earlier mistakes.
So, the strong recommendation to give customers between a /48 and a / 64 (and /64 even for a single machine) - is the right way to lay the foundation of a new address space exhaustion
If the Internet doles out a billion /64s every day -- several orders of magnitude more than any forseeable assignment rate -- it will take 50 million years to deplete the IPv6 address space. I'm happy to leave that problem to the next generation. :-)
