Yes there maybe some common sense approaches to curating things but Reddit has gone too far IMHO.
I think HN is a separate use case than is reddit. Which is why HN will never become Reddit nor does it want to. It's always been a niche site. Even though it's gained quite a bit of notoriety in the last decade. Most people outside of tech circles have no idea what HN is.
It's less of a separate case from a single subreddit in many ways. (although of course a subreddit can't influence a lot of the things that are differently designed on HN, so it's not like you could turn it into one and it'd just work)
