No it doesn't, because I define all ads as bad, so Chrome's ad "blocker" is does not even remotely meet my needs.

That "just" is doing a ton of work there. Declarative ad blockers aren't terrible, but they're not great either. And I don't want my browser fetching ads (which could also be malware) at all. Downloading them and then hiding them is insufficient.
