Dutch tech news website Tweakers.net basically has this. Comments are moderated on a scale from -1 to +3, and then you can choose to expand only +2 and up.
I have it set to 2 by default which helps but can also be annoying on fresh posts as unmoderated posts are also hidden. And then if there is a +2 post it totally only makes sense in the context of the tree so now I’m manually unfolding the parent comments.
All of this to say that one feature brings in a whole set of additional complications. Less is more.
