I’m by no means a test police. I’m in fact opposed to a lot of mindless testing for the sake of it. But there are places where unit tests shine, and this is one of them.

If you mean that criticism is only allowed if you are willing to commit labor, I disagree with that. I always welcome critique myself - it may be something that I’ve missed. The maintainers always has the last word. As long as there are no hidden expectations, it’s all good.
