Your information seems to come from a pre-print on MedrXiv [1], but not all your claims are supported. Especially the spreading rate and "deadliness" of the new mutation are not mentioned in the paper. The paper (which has not been peer reviewed) only notes the discovery of this new mutation. If you have other sources, I'm open for more information.
If you are wondering why D614A is not mentioned in the Nature article: the preprint has been out for 2 days (Nature published yesterday) and this information is only based on a single pre-print, not a peer-reviewed scientific article. I don't think saying "who cares about obscure -stans" is fair towards the author of this article.
