You’d still need to solder components to the posts, and only then you could do the wirewrap connections between those posts. It just doesn’t make any sense. I believe even “back then” the wire wrap was only used on backplanes; modules plugged into those were through-hole PCBs plugged directly into the posts that were wrapped around in the other side.
