Also, we may be able to create those packages from parts of browsers, which wouldn't be a re-implementation, and would benefit from the rigor of the standards.

I agree that it would be kind of silly to then put this in the browser. Instead, I think it could be used to build the native target. And just to clarify my earlier statement, I'm not a fan of phasing out the use of the DOM in the browser— it has graceful degradation and accessibility features that are really important. It's more that there are people with existing Qt or JavaFX or Cocoa dependent projects, or whatever, who are now able to deploy to the web by implementing the UI layers in WASM/WebGPU.
