No, because subthreads like this are eternal and no effort to prevent them can succeed. They can only be somewhat contained sometimes. If moderation mechanisms need to be changed, it needs to be for more substantial reasons.
Each generation of internet users thinks they're the first to come up with these things, and in a way they are, it's just that every previous generation was also the first to come up with them. It's an eternal cycle of internet forum life. The points you raise have been raised on HN for over a decade (HN Search is your friend!) and if they weren't those points they'd be others.
That probably sounds too dismissive. I don't mean that we're uninterested in hearing from users, getting suggestions, and answering questions. We do that all the time, and it's welcome. But making meta-posts to HN is not the best way to do it, especially in any inflammatory context, where they are almost guaranteed to blow up like the gas station in Zoolander—and then consume all our limited resources for the day, which ought to be going into making the site better.
