One of my customers was handing out /64s for a while but it was more hassle than it was worth. I only ever saw one residential customer use it, and he was just smart enough to cause problems.
Its one of those things that there needs to be strong consumer demand for, or it will just never happen tbh.
From our perspective, what we want more than anything in the universe is to never do NAT or DNS ever again. I would much rather maintain a billing system indicating you rent a small block of IPV6 space, with a nice little static route, over maintaining never ending NAT and DNS logs for the benefit of police forces who cant shit without collecting every micron of data. But NAT is basically security these days, and theres a negative driver in exposing customer routers directly to the internet (in that, if it even supports v6 its likely to be rooted) Customers will leave if telcos do things properly, and theres literally zero reward for being nice about it.
Interesting, my two ISPs (one in Belgium, one in France, not business ISPs) hand out fixed /48 blocks to every customer. As far as I know, that's what RIPE recommends, they actively discourage from assigning longer prefixes than /56.
The modems they provide handle it without needing anything special from the customers. The devices get IPv6 addresses from this prefix, and are firewalled by default. It's pretty simple so I'm not sure what could go wrong there.
