Internet is always "best effort", we are all always reduced to the least common denominator for network quality. I would say networks that only have ipv4 are not doing their best effort. There will not be suitable truly ipv6-only offering in the next 10 Years because of these laggards. That said, buying ipv4 makes me feel ill. Please put ipv4 where it belong in the cgn / nat64 / MAP br / aftr. Ipv4 is not premium, it is legacy services deployed by companies on a downward slide. .
