I think it rather depends on your definition of "adult" here. The point has already been raised that the policy change affects things like skin textures. The sale of sking textures perforce involves nudity, but there's nothing "adult", in the sense of X-rated, in simple nudity. If the fuss were entirely about sex-toy props then maybe. But when you get into the proportions of flesh that may be visible, we are getting into worrying territory.
