As a maintainer on the Ky team, I give a big thumbs up to this proposal.

We have run into many problems with web streams over the years and solving them has always proven to be hairy, including the unbounded memory growth from response.clone().

The Deno team implemented a stream API inspired by Go, which I was happy with, until they ultimately acquiesced to web streams.

This proposal shares some of those principles as well.
