If we changed focus to reliance on web standards rather than complex build systems like react it would help. The idea that you have to compile JavaScript comes from all these people coming in from CS programs into front end. You don't need to compile standard compliant Js. Most people use chrome so in fact web components are widely supported but hardly used.
I agree in principal that we need to make that simple. React can work without a compiler, but it wouldn't be as pleasant without JSX. Same goes for the rest of the stack, there are so many DX improvements in either using SVGs as components, or simply the dev profiling / debugging.
