The very next sentence of the post you quoted states that “Hubitat Elevation does not currently support commissioning…”
I don’t have any inside knowledge one way or another, but to me that suggests in the future the hub could support commissioning?
Also AFAIK that’s unrelated to concerns re: IPv6 networking. And I agree with others that the overwhelming majority of consumers don’t need to worry about how matter devices will interact with a complex setup of multiple VMs, VLANs, WiFi networks and tight firewall rules because they don’t have any of the above at home.
