I believe that passthrough should be kept as core Xen, it is small and quite tight to the rest of Xen.
It might be.

But I would be interested to know what would be the rationale to disable that. Do you foresee certification on IOMMU-less platform?
I would give TI Jacinto6 as an example. It is an automotive focused SoC, has no IOMMU. BTW, I have a strong feeling that some J6 based automotive systems with XEN already reached production stage. I'm not really sure if they are certified, but anyway. So, yes, I'm pretty sure IOMMU-less platforms with XEN would require certification.
