I see three lines of addressing this concern:
1) Anatomy was over a long time under strong evolutionary pressure. Human intelligence is a fairly recent phenomena of the last 100,000 years. It's a mess that's not as well ordered as anatomy.
2) Individual humans deviate more from the textbook anatomy than you would guess by reading the textbook.
3) The brain seems to be build out of basic modules that easily allow it to add an additional color if you edit the DNA in the eye via gene therapy. People with implented magnets can feel magnetic fields. It's modules allow us to learn complex mental tasks like reading texts which is very far from what we evolved to do.
And yet textbook anatomy is my best guess about a body when I haven't seen it, and all deviations are describable compared to it. What I object to is the norm of treating phenomenology, such as the observations about magnets and eye color, as more-or-less solid background for predictions about the future. If we discuss, say, artificial new brain modules, that's fine by me as long as I keep in mind the potential problems with cranial pressure fluctuations, the need to establish interconnections with other neurons - in some very ordered fashion, building blood vessels to feed it, changes in glucose consumption, even the possibility of your children cgoosing to have completely different artificial modules than you, to the point that heritability becomes obsolete, etc. I am not a specialist to talk about it. I have low priors on anybody here pointing me to The Literature were I to ask.
I think seeing at least the bones and then trying to gauge the distance to what experimental interference one considers possible would be a good thing to happen.
