The NBD server uses an AioContext notifier, so it can tolerate that its BlockBackend is switched to a different AioContext. Before we start actually calling bdrv_try_set_aio_context(), which checks for consistency, outside of test cases, we need to make sure that the NBD server actually allows this.
