Let me move this one out of draft, but please have a close look to see if the approach makes sense. I recall I was fiddling a bit with passing the context with the combination of closures and call-sites of different parts of the code.

Ah, one more thing, can you please add the changelog description with highlighting the API change?

EDIT: Sorry, I confused PRs 🙈 There was no API change in the end here (we didn't alter the RunPlugin signature), so no need for changelog!

@vvoland You had the PR right, I just reverted those changes in the PR and squashed the commits
