Mv3 blocking has some advantages, and may be enough for most people, currently, at least until things escalate. Mv3's blocking capabilities are similar with Safari's, and have the advantage of performance and security.
This extension is Mv3 compliant and decent enough. It blocks Google's trackers and ads, it blocks YouTube ads.
Also, keep in mind that other Chromium browsers have ad-blocking built-in, e.g., Brave and Vivaldi.
And Google's problem will be that all of Chrome's competition will have better adblocking as a selling point (except for Edge). So they can't keep Mv3 functionality too ineffective.
You can see it for yourself by trying uBO Lite:
