Perfect intersectionality is a goal, an ideal that we can be measured against, but there must be a transition to it because we are not there in many ways. Places holding themselves to a strict or impossible standard are probably hurting themselves in the short term, but I still think that it is a good goal to work toward.
Fast, normal, and slow are not clear either, I think. We see here that the “fast” term needs to evolve because it probably feels pretty slow now. Wattages are pretty clear reference points when users come to understand what they mean, especially over time.
