> This is probably mostly useful when downloading many small images. It's useful for much more than that; I'd actually argue stream multiplexing is most useful outside of the browser in bespoke HTTP APIs, because that's a place where you can just stumble on cases where high fan-out requests are useful. For the browser case you're often limited by things like pagination, while JS/CSS can be amalgamated. Not that it isn't good for small images too! But APIs benefit a lot as well and I think that's easily forgotten.
