If you want compilers to be able to natively target browsers and access the browser DOM APIs, then you need to define some kind of contract between browsers and compilers on how to call APIs in one from the other. That is what the Wasm Component Model provides.
Perhaps some people are happy to keep the status quo where each call between Wasm and the browser needs to roundtrip through a JS glue layer. But personally I'm excited about a future where that is no longer needed.
