How about nutrition profiles? We've seen huge vegetables and fruits at the super markets, but their profiles suck compared to conventionally-grown, but usually smaller plants. If we only focus on rapidly growing biomass sold per weight ignoring the main reason we need plants - their nutritional benefit, we're going nowhere. Also, we know from some research that the more a plant has so struggle, the better its micronutrient profile is. Such example is the connection between grapes, climate, and resveratrol content.
