The issue is a little deeper than spanking it to anime titties, and it's a disturbing trend in puritanical self censorship in order to appease the moral busybodies & the ones they profit by. It's a 2016 mindset and the market has moved past it. It's time for companies to dismiss the pearl clutching as well. Saying 'ok in Japan but not in America but we want to sell to both' is talking out of both sides of your face. Pick a lane.
I'd guess this is a Capcom initiative. SNK probably wants to broker a new long term partnership with Capcom and in order to do that, they have to be willing to roll modern Capcom style where it concerns their crossover products. SNK has, until this point, displayed an utter lack of regard for the moral panics we see in the west. Even City of the Wolves is leaning into it with B. Jenet, and KOF XIV and KOF XV both embraced that old school sexed up aesthetic.
