> Address stability. If you use the prefix your ISP gives you via DHCPv6-PD or whatever, it might change on you, and then all of your hard-coded configs are wrong.
Right. I've been using my own address space at home for a while now that I've forgot how dumb ISPs can be.
I've got a BGP session on a VPS that's located in the same facility as my ISP (my upstream and by ISP are even peering there, over both, v4 and v6. The only thing missing for me is IXP access, which the VPS provider offers, at €50/month, so in this instance it's not worth paying for, but damn I'd love to give my own ISP the routes to my home network myself), so I'm just running a WireGuard tunnel from that box to my home (mainly because my ISP still doesn't offer any IPv6 whatsoever). This setup actually costs me less than a static IP from my ISP would. They charge €15/month for a static IP. My setup costs me €6/month for the VPS and additional €5/month for the BGP session.
I could even do iBGP between the VPS and my home router over that tunnel, but that's far too hardcore. I think the /56 I've given for my home network will be enough for a couple of lifetimes. After all, it's 256 subnets of /64, and how many VLANs do I need at home? :D

Unfortunately not everyone can do this. :(
