So our next task is probably getting us a way to have options in QAPI
that aren't exposed in QMP. You added some of these non-QMP options to a
block driver yourself only recently, so you probably already know of and
understand the need for it. If we ever get QAPI for the command line,
this might actually be a third set because I think we have some options
that are only meant to be set internally, but never from either QMP or
the command line.

Once we have support from QAPI to consider the context when parse
structs (i.e. reject non-QMP fields when parsing QMP commands), we can
look into converting the block layer step by step. I'm not sure if this
is the only problem we have (I would be surprised if it were), but it's
the big one that I know of.
