> able to tell real issues from non-issue discussions

imo almost all issues are real, including "non-issue" - i think you mean non-bug - "discussions." for example it is meaningful that discussions show a potential documentation feature, and products like "a terminal" are complete when their features are authored and also fully documented or discoverable (so intuitive as to not require documentation).

99% of the audience of github projects are other developers, not non-programmer end users. it is almost always wrong to think of issues as not real, every open source maintainer who gets hung up on wanting a category of issues narrower than the ones needed to make their product succeed winds up delegating their product development to a team of professionals and loses control (for an example that I know well: ComfyUI).
