Web stream implementation

[ecofi]

I posted this also to sax.js but I noticed that saxes the more recently active fork

Is there an chance to implement web streams so that we can use it in browser with fetch response directly? This would be really awesome and because nodejs is now also implementing web stream API it could be the approach for having a single stream implementation.
I'm looking for something like this:

fetch("very-large.xml").then((response) => response.body.pipeThrough(saxWebStream))
