Issue trackers should be used exclusively for earmarking and tracking the progress of actionable items. This is somewhat similar to the integration between email clients and task managers, like how it's done in Gmail, Zoho, etc. You read the message first. If it requires an action from your side, create a task from it and link them.
There are other projects that do this too. A good example is the 'mise' project. Sourcehut projects use this workflow almost exclusively since it's the default by design. I think sourcehut had if before github did. What I would like to see is better integration between discussions/messages and task/issue lists on all these platforms.
