Yes, but if there were other metrics to measure what deserves rewards apart from Quality and engagement in the post, then I think the reward pool distribution measures - those that we support or we don't - would perhaps change and adapt to the new common agreement.

I absolutely agree with this. However, even if such metrics existed, under the current protocols, one whale account can still wreak havoc, with impunity. The “with impunity” part is the problem. There are no robust defenses against such abuse.
