Normally we try to make these things work grammatically. I don’t understand what “readable stream is pull requested” means. So I would expect this to have some other name, like “hasRequestedPull” or whatever would be the colloquial or standards language way for talking about the state of the stream.

OK. stream spec is now using "pullAgain".
Let's call it "shouldPullAgain" then.
