Cool! Perhaps the v3 patch is no longer needed IIUC, given that Nikolay's
migration refactor series fix the backward compatibility issues with the
different protocol versions for drivers implementing only v3 params (such as
libxl and vz). For example, ToURI2 works now without v3 support.
Thanks for the time reviewing this series!
