This is undeniably true though as I am tasked as the security monitor for several tiny LANs, NOT letting every device have DMZ access has its advantages.
Maybe I'm just too greybeard to want to change. I love IPv6 for infrastructure and personal devices. For my home LAN and those I am responsible for, a tightly nailed down IPv4 environment is what I prefer.
I'll leave the massive address space and IoT readiness to you young and upcoming packet jockys, and in my retirement will marvel at the wonders you create.
For now, you'll get your DHCP and you'll like it if you want to stay in my house young man!
IPv6 is all well and good until you need to read of an IP address for a call or write it down if you don't have copy-paste UI access.
Then you will pine for the days of four octets.
