As usual from Chrome, 100% ignores the fact that developers have wanted to use fetch to be able to reactively hear of resources coming in, & chrome has (largely) ignored these pleas. The post focuses only around the most boring & basic capability of webpage loading, since that was the only capability developers ever got.

The article talks about Jake Archibald enumerating some problems with PUSH. Well, Jake was also author to a mini-proposal to add Push support to fetch so developers could try out other uses for push. Seemingly ignored by chrome.

Having the browser be a minimalist, picky implementation of http protocols is hard for me to reconcile & be ok with. There's well over a half decade of neglect & plugging their ears on Chrome's side around Push, not listening to users, not delivering us low-level extensibility manifesto capable apis, and this pulling the plug is sad and sorely premature.

We are stuck forever inventing new non-http transports, over SSE, over websockets/webtransport, over long polling, becayse Chrome systematically ignored the one thing that would have made http capable of satisfying many of the desires of the old HybridBidirectional working group, & has kept the page unable to understand & recieve resources coming to it. What a blasted shame.
