This is really a good issue if someone wants to dig into how streams work. I'm happy to help.

Hi, I am interested in the internals of streams since folks in my company have bumped into some perf issues related to it. I would love to spend some time digging into it and learning how it works :)

I have attempted a PR for needReadable(#10241), please take a look.

Since there is #10214 involved I might need a little bit more time to get my head around emittedReadable.

@joyeecheung I would like to have a test for emittedReadable before a fix for #10214 happen. I would like to track possible regression, so write a test for what it is doing now.

Yes but not entirely. We can close this in fact, my bad.
