I don’t agree with that framing.
All metadata has been preserved and published, and the sucessor sites to what.CD have long outgrown it; and their successors will again. Anything you find missing, you can request and typically it will be filled within less than 24 hours.
And i also truly cannot understand what your point is. Trackers are not really legal, they come and go. I don't think a few hundred or even a few thousand HN users joining across the ecosystem is going to suddenly cause them all to get raided
