No. People actually read it and think that it's not intended for
generic purposes, i.e., it was designed for VT-d/AMD-IOMMU with KVM:

You designed it for what you need at the time. It should have been
named appropriately to avoid confusion. Later, when we actually
understand what other IOMMUs need, we can evolve the specific API for
generic purposes. Then we can rename the API to more generic.
