Ah, that makes sense. Too bad it will uglify the already unpleasant

Are you planning to do something similar for the dom0_op structure?
No, it's too big so too much hassle. Also I added padding to it some time ago so the union is hopefully big enough for future use and, if not, we can always link out to a secondary structure for some subcommands. So it's the only remaining union-style hypercall and it's here to stay.
