For the record, even though we've made the official change, the whole thing regarding NU is still being looked into. If we can be assured that NU beta comes out soon-ish (like stats within the first week of the month), we may just reverse the decision, since there's no reason to really remove an official metagame. No promises at the moment though, which is why we made the pre-emptive decision of BSS. If there's no further updates, assume that BSS is final. Hang tight.
