Not at the moment, CCing people who might know more about the topic.

But just thinking about creating QAPI schema for devices, it's not really
possible to generate one using dynamic properties (unless one resorts to
creating every supported device instance), while arrays of static properties
are there for every device and simplistically speaking just need conversion
to schema format.
