TODO: We also need to deprecate drive-backup transaction action..
But union members in QAPI doesn't support 'deprecated' feature. I tried
to dig a bit, but failed :/ Markus, could you please help with it? At
least by advice?
This is one way to resolve it. Sorry it took so long.
John explored another way, namely adding feature flags to union
branches. Could also be useful, say to add different features to
branches in multiple unions sharing the same tag enum.
