Is there any reason we really need to care what size other people use for their Point to Point links? Personally, I think /64 works just fine. I won't criticize anyone for using it. It's what I choose to use. However, if someone else wants to keep track of /112s, /120s, /124s, /126s, or even /127s on their own network, so be it. The protocol allows for all of that. If vendors build stuff that depends on /64, that stuff is technically broken and it's between the network operator and the vendor to get it resolved.

please explain why this is in any way better than operating the same LAN with a subnet similar in size to its existing IPv4 subnets, e.g. a /120.
Using /64s is insane because a) it's unnecessarily wasteful (no lectures on how large the space is, I know, and reject that argument out of hand) and b) it turns the routers/switches into sinkholes.

Most software today is very much like an Egyptian pyramid, with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves.
