I see where the confusion lies. The guide misuses the term "NNID" which is, as you said, only for the Wii U and 3DS. The Switch uses the Nintendo Account system which I can assure you is different than your NNID despite how similar they sound. If I had a GitHub account, I would either open an issue or submit a PR to clarify the wording. Either way, I would still recommend linking an account as certain games will not work without one. One account is sufficient for an entire household provided you're willing to share it with your family.
So after I create a Nintendo Account (just needed for playing local multiplayer games) at what point do I log into that account on my Switch? After I've blocked the Nintendo DNS and done everything else in the switch.homebrew.guide? Won't the DNS block me from signing in?
