I agree. And in hindsight, the PR I linked was a really bad example for what I meant to convey.
Perhaps my proposed solution is inherently flawed, I agree with most of what you’ve mentioned. My focus was more on “something needs to be done”, which I really don’t see anything about. An example is this thread I opened with my last comment being regarding onboarding, as you mentioned.
Of course, things take time; that unfortunate PR happened to be my tipping point with all of the other issues which go beyond one-off mistakes (they are very much systemic).
I don’t mean to be a misanthrope and I hope my words aren’t read that way either (given they sometimes unintentionally sound that way 
). We’re all part of the same team trying to make this better
