Thanks!
We will publish in the next week a first implementation of SMMUv3 support which might make sense to have fully Supported.
I am not sure whether you include security supported in your "fully supported"
However, I would consider to follow the same model as we did with the IPMMU. The driver would first be marked as a technical preview to allow more testing in the community.
