I don't know that I will ever be happy with lazy loaded UIs over a more traditional "Deliver everything first, update later" approach. Hopefully Suspense is a step to solving the problem. I live in Australia, so there's a perceptible ~300ms delay for every action in react-like loaded later UIs that aren't hosted in Australia, which is most of the tools that I use. They feel clunky and broken, and the amount of times you miss-click because something pops in suddenly and moves the button you wanted down the page. I don't think it's the UI they think they've built. I don't think it will ever be good enough to throw 20 requests and wait for everything to update, bounce the page around and at long last be intractable. I would rather receive a 2mb page right now, than a 200kb page that slowly grows to a 2mb page over the course of 20 components individually loading themselves.
