Oh, yes, IPv6 saves you from worrying about addressing, which is a huge headache in IPv4. I agree with that and IPv4 address conflicts are a personal frustration. IPv6 doesn't save you from "fancy routing" and mostly does not save you from "nat," though. That's what I was responding to.
I'm hesitant to use IPv6 because it is not merely IPv4 + more addresses, it's IPv4 + more addresses + a very clever design that hides the L2 vs. L3 distinction by relying heavily on multicast groups + a replacement for ARP + a replacement for DHCP + etc. etc. etc. I know I shouldn't be using IPv4 in 2019, but I don't have a better option. I'm not excited about clever systems, hiding, the assumption that multicast works reliably, losing the last few decades of monitoring and debugging tools, happy eyeballs, etc., and I'm not willing to subject my users to the resulting outages simply because it'll save me the headache of thinking about numbering.
