Markus has been trying to eliminate the addition of new "simple unions"
- while they are syntactically shorter in the .json file, they are
bulkier over the wire with extra {} nesting, and more verbose in the C
code, when compared to using a flat union instead. I won't necessarily
hold up this patch as-is, but if we are going to avoid new simple
unions, we have to change this before 2.9 bakes in the {} nesting (we
can convert a simple union to a flat union without breaking QMP
back-compat, but it's messier than if we avoid the nesting to begin with).
