Ah, okay, well if you already have the IPv4 address space available for all your customers that's a different story. I can understand why you want to wait to dual-stack in that case.
I do think NAT64/464XLAT is a pretty good architecture for new ISPs that can't get their hands on IPv4 space, though. Or even MAP-T, but CPE support isn't really there yet.
CPE support is the issue and has always been the issue! People assume that IPv6 is done, but it really isn't in the consumer networking gear product space.
