All true, and we (content blockers devs) were saying this all for years, since MV3 was first announced. MV3 brings very little (if any) privacy and security enhancements, this is for the future MV4 when extensions will be dumbed down to sets of declarative rules.
We'll now need to rely on Chrome team for implementing what we need. But they do it painfully slow or not do at all.
Also, where will we get the new ideas if every browser follows that path? Take Safari for example, every little improvement that we requested [1] was inspired by what we already did in other browsers long ago.
Anyways, a working content blocker on MV3 is possible. I even think a casual user won't feel much difference. But there is a big difference under the hood and to feel the consequences we have to wait a few years.
