There are couple topics at present that would be suitable to raise at
the EU-US friendly time. Specifically whether all of the per-arch
implementations of "transport large attestation evidence blobs over
shared memory from host-to-guest" would be better served with a shared
generic transport (simple virtio-pipe / something equivalent for vmbus
to publish).

Then there are the next steps with the uapi to convey PCI device
attestation that was proposed here [1], and also discussed as part of
the Rust SPDM proposal [2].
