I hear you. I think it's important to lead by example here and demonstrate the value of performant software that is accessible to a wider range of users/devices.

Native apps do demonstrate that there are performance gains to be made with languages better suited for runtime performance (think threads, AOT compilation, etc)

Just because there is currently a culture in the web development world that de-emphasises the importance of performance, doesn't mean we shouldn't strive to offer better tools to developers.

Right now, wasm is the only feature on the web that has the potential to offer that capability to developers - so I'd say that it's worth wanting and asking for the choice to use better tools for web applications.
