Berrang=C3=A9 We could in fact add a further version of all the CPU models which adds the "ssbd" / "virt-ssbd" and "mds" features, so that there's a version apps can pick that covers all the currently known hardware flaws. Anyway, it can be done as a patch at the end of this series or separately as desired.
