There are some people who see the web as a platform, and some people who see a web browser as a window for zero-install applications to draw into. There have always been people in the latter group who try to abstract everything away, but it does tend to discard pretty much everything that makes the web great.
A lot of what Next does/did _is_ leaning into web’s strengths. It was Next that made me declare image size beforehand, for example, drastically reducing layout jumps. It also made image optimization almost effortless, greatly improving load times for my websites. The web as a platform is a nice concept I would love to adopt more, but then I need to write some server-side code and I am completely on my own. Pushing the DX around the client/server boundary is one of the things that made Next great for me.
