What NetBSD's focus is to get it running on all possible hardware so yea that's why they really haven't gotten it to be much more different than any of the other BSDs. Since OpenBSD's purpose is to make one of the most secure UNIX platforms that's where they generally break things. They also anticipate security holes related to speculative execution like disabling hyperthreading.
