> It may not be % DV, but off the top of my head, say relative sugar ratio to other food products in the same category. But that can be gamed as well since there're only a handful of independent companies in the industry.

Right now, there isn't sufficient medical consensus to require labeling. A metric that is trivial to game can be far worse than not having one at all, as is picking a metric that ultimately turns out to be incorrect and counterproductive.

We know that, broadly, "too much added sugar isn't good". But we don't know exactly how much, or what the tradeoffs are with "replacing" added sugar with natural sugar (by substituting foods in diets), or with replacing added sugar with various sugar substitutes, or even if there is a meaningful difference between the different kinds of sugar (sucrose, glucose, fructose, etc.). There are speculations with some evidence to suggest reasonable hypotheses, but prematurely acting on those hypotheses has very far-reaching consequences.
