Most userland implementations of custom ReadableStream instances do not typically bother with all the ceremony required to correctly implement both default and BYOB read support in a single stream – and for good reason. It's difficult to get right and most of the time consuming code is typically going to fallback on the default read path. The example below shows what a "correct" implementation would need to do. It's big, complex, and error prone, and not a level of complexity that the typical developer really wants to have to deal with:

It felt like a page that only I would find useful. So I started over and designed a “concepts” page. In redesign 4 I focused on what effects I wanted, how SDF works, and how to use it to create those effects. I again reduced the scope by removing the implementation details. What I had already written, I moved to a separate (unpolished) page. And I never wrote a standalone downloadable project like I originally wanted.
