In the United States, the role of a central bank is to manage two measures: inflation and unemployment.

The US Federal Reserve Bank does not measure inflation or unemployment. Rather, the US Department of Labour, an independent organisation (and a branch of government rather than a freestanding entity) computes both measures.

This is the principle of division of responsibility and measurement or judgement. You cut, I choose.

Google are both measuring, and rewarding, website performance, as well as designing and distributing the principle tools that benefit by both choices. That's an extreme locus of power. And, history shows, generally a Bad Idea which Ends Poorly.

Also given their market share as a search engine, they also get to decide which websites you will be able to "discover" additionally incorporating their performance metrics into their website ranking. So not only a website will get a "slow badge" but will also be downranked into oblivion.
