Fair enough. I can see why you might want to make it sit below other comments. It's a pity it hides it though as some people may benefit even if they don't say about it.

To me, the benefit to people who might benefit outweighs that but I can see where you are coming from. I might have a look and see if there is a way to make them comment on my posts.

I've seen the comment thing about HF21 a bit though, but don't know enough about the changes to fully understand the situation there. Why can't people upvote comments? I can theorise based on what else I know about the changes but I don't know if the things that seem as possible reasons are the actual reasons or not.
