Then opening the ticket should be easy enough?

I certainly understand the maintainer here, because that’s what I keep telling colleagues at work.

Tickets get really cumbersome if they are not clear and actionable.

Exactly, that's all his PR had to be. The history of finding the issue could be an interesting story (I bet it involves Elixir!), but in places it reads as almost malicious. If I received a PR anything like that on something I maintained, it would be received very poorly. The author comes off as overly aggressive toward the maintainers and far too sensitive to their response.

...that's what they are asking, yes.
