A dead response notes that IPv6 makes blocklists intractable as IPs can be rotated at will until doomsday with few consequences.

The response in this case will all but certainly be an increasing tendency to apply IP-level whitelists, and deny or at least limit traffic until it's demonstrated trustworthyness.

Much as port-based firewalling progressively closed off virtually all service access other than HTTP/HTTPS, and a few other exceptions, bad actors will likely limit the effectively-reachable scope of IP address space itself.
