Although payload can be indicative of page load speed, there are many good reasons Lighthouse scores are more complex than that. Specifically, at the start of this thread the criticism was that the js work in modern web apps is slow. I have thus far managed to avoid using react so I don't know the actual numbers, but I don't think the conversation should be reduced to payload size, even if it is obviously important. When I profile problematic pages, other than sites that don't properly scale their images, it is not usually network that bogs them down, it is the rendering.

Even focusing on Lighthouse score or similar for a basic app is totally missing the point of Nue as presented on the linked page. It about a framework designed for speed that can handle data at scale, that is easier to control and personalize, and easier to model and thus architect. And yes, of course, most any framework can be used for good work, but the relevant question here is which one promotes it the most from start to finish, and makes it the easiest to implement. Speaking only for myself, this focus is great to see.
