Been running IPv6 for years on both my home network and internet servers, and I've never had to think about NDS, DAD, RS. SLAAC is something I've only had to think about once at network setup time, less than I think about DHCP on my IPv4 network. RAs I have actually had to think about because Unifi has had some regressions in IPv6 support over the years, but that's fixed these days so it's likely going into the "don't need to think about it" bucket too.

Of course I'm sure you think about DHCP address management, DHCPDISCOVER and DHCPOFFER packets, mDNS, ACD, etc., since clearly you like to get into the weeds of your network
