The title of Go's GC announcement is "Go GC: Prioritizing low latency and simplicity", and I think that a variation of that would be a better title for this. Some users may prefer a different tradeoff, and I think it's important to know that there is a tradeoff. But as this article says "I have no doubt that many Go users are very happy with the new runtime.", and that seems like a worthwhile metric.
