If you see a situation where a canned comment doesn't seem appropriate for a particular question, either insufficient explanation or just wildly wrong, you can leave a personalized comment. I see that I can leave a comment on the linked question. This is probably related to points earned, which are necessary to even see deleted questions, but you have more than I do anyways.
My understanding is that questioners will see comments on deleted questions, but if I'm wrong, hopefully someone will correct me. If they can't, that's not good design.
I try to leave comments when I vote to close a question, because canned responses seem rude to me. We are humans, not robots, and other humans deserve our personalized explanations, no matter how abstracted they seem on the internet. However, I don't always. Sometimes I recognize that this isn't a time when I can be diplomatic enough; other times, I'm simply lazy. But I think it's the decent thing to do, and I make some effort toward it.
I am not a fan of BSE putting words into my mouth. I'm happy to attach my identity to an initial close vote, but not to the words, "Does this answer your question?" I would much rather BSE offered those words and allowed me to say something else, provided I still gave the appropriate link. I would still sometimes just let BSE say that on my behalf, whether out of recognition of my own bad mood, or out of laziness.
