You might have missed it in all the links but the data set and its maintenance is a Google thing not an HN thing so those are the people you need to get in touch with.
So I assume your feedback is official right? I understand now that it could be an interesting contribution to have a similar database to be used, for example, for machine learning? Do you agree?
"random internet busybody" official, yes. If you want to talk to HN people about it, you can email them, I'm just pointing out their description of the situation is already quite plain and public.
