Define end0-site. Residential customers, for example, don't need more than a /56. More would just be obscene. Most small businesses don't need more than a /56 either, especially if you are breaking them up into different sites (versus assigning a /48 to customer and dividing that block up to different sites).
You are wrong. Residential customers should get /48s. /56s seemed like a good idea at the time, but, they aren't. It's not just about counting subnets. There's also the issue of needing bits for self-defining hierarchical topologies. 8 bits isn't enough for that. 16 is. Seriously... This isn't IPv4. The scarcity mentality is causing harm and driving decisions that will have a limiting effect on innovation that is already in progress. Owen
