Feels like GitHub issues needs states other than Open or Closed. How about:

Resolved - issue has been fixed/addressed

Won’t Resolve - addressing the issue is not aligned with the direction of the project; it is not and will not be resolved

Paused - issue is valid but no one is continuing to discuss it, explore it, or work on it at this time; someone can resume the issue if they have new data or ideas.

Maybe issues aren’t just “tasks” but they’re part of your work, and you need some tools to prioritize your work and help communicate to yourself and others what you’re focusing on and what state things are in.
