I think that it's super nice if we can have this automation (in contrast to running tool manually) but I wonder about few things

1. I would argue that after closing the issue some labels (like type: or "stat:imported" or port: or priority: or "regression") can be useful from "history tracking perspective" so I wonder if we could remove all BUT those for example
2. With the "autolabel" workflow I believe that at the end we came to the conclusion that "stat:awaiting response" label should be set manually (to avoid adding this label when not really waiting for response but rather commenting on the thread)

What I was thinking in general are the following rules (included in this manual tool):

1. Remove "stat:awaiting triage", "stat:awaiting response" and "stat:Investigating" labels from closed issues (this list could be expanded or modified depending on which labels we want to keep/remove)
2. When a person is assigned to an issue, the "stat:awaiting triage" label should be removed. IF label “import” or “imported” is not present then label “stat:Investigating” should be added
3. When an issue is not assigned to anyone (someone de-assigned) label “stat:awaiting triage” should be added. IF label “import” or “imported” is not present then label “stat:Investigating” should be removed
4. When label “import” or “imported” is present then labels “stat:awaiting triage” and “stat:Investigating” should not be present
5. When "stat:awaiting response" is present but Issue owner replied to the thread after this label was added, remove it. (This means that we are no longer waiting for the answer)
6. When an issue has “stat:awaiting response” tag for two months, add a “stale” tag.
7. When the issue has “stale” label for two months (four months in total with no response) report it (somehow) so it may be potentially closed.

Does this make sense? Could something like this be implemented in GitHub workflow?
