Maybe "issue" should then be renamed into "TODOs". Because end users have "issues" with a product, it is up for someone with more knowledge to identify if the "issue" is PEBKAC, WONTFIX, FEATURE, or actually a TODO for the developers.
The term "discussion" does not have anything to do with this.
I understand these are all github choices of terms, and it should also be reframed properly by github.
