I'd say just go ahead.
While I appreciate the sentiment, I would rather not have an excessive amount of detail added to this page.
The idea behind it was to show users that they shouldn't expect the address in the domain XML to match the one in the guest OS, with a few real-life examples to illustrate the point. So, I don't think the details of how exactly zPCI IDs translate to guest-visible PCI addresses is in scope.
It would be great information to have in some other document, though! Is there something like that in qemu.git, or in the QEMU wiki? Those are the places where I would expect it to live, since it's not really tied to libvirt...
I don't think there's much in QEMU documentation yet; someone(tm) wrote https://virtualpenguins.blogspot.com/2018/02/notes-on-pci-on-s390x.html, which might provide a starting point.
