The thing is most companies would want to have a web presence anyway. It's just easiest exposure and people have to be willing to install a software - visiting a website not so much. So if you're building these cross-platform apps on anything other than the Web stack people will still have to have different code bases for native and web which kinda defeats their purpose.

So I don't think you have any real alternatives until there's other technologies on the web or wasm can do everything.

As I kind of alluded to in my comment, I'm not sure many of these things need to be web apps. OS level sandboxing has come a long way in the last ~10 years, and need fewer of the benefits of the web (like publicly addressable resources), and more of the benefits of desktop apps (like filesystem access). Web tech is improving its support for the latter, but I think we could do better if we designed a system today, rather than using one mostly designed between 95-05.
