Qt's accessibility framework also needs to be able to present this information via at-spi to accessibility tools such as Orca.(1) This is probably something that is more to do with Qt internals working with Mir, but even though this is primarily about autopilot, keeping accessibility requirements in mind when thinking about this is probably also relevant.
