This sounds good, I think rpmsg bit was the initial part of this that I was missing (but that will then lead into requiring the others) - this is essentially VFIO for a software defined component so it's clear that there's value in standardization on the discovery and transport parts of things but I agree that the actual messages are just a vendor thing and don't need an OASIS standard.
