The original design of the WWW has morphed a dozen times between what he built and what we have today. And while I don’t love every innovation, there are plenty of things we take for granted today that wasn’t possibly with HTML1, such as banking apps.
So I don’t think there’s much merit arguing about what doesn’t exist any longer.
Banking apps are not “websites” by coincidence they happen to be apps using same technology to show the interface but there is huge difference between website and web app.
This distinction is important especially because people are notoriously confusing the two and expect web apps to be like websites and conversely implement websites with tech that is supposed to be used to build web applications bloating internet pipes with JS where HTML and CSS would be sufficient.
