I don't think we have that today. Also, I'm not sure if that should be
block device backends or actual block devices. If you mean the former,
then backends that are not connected to a device yet will appear; if you
mean the latter, you should probably ask qdev/QOM rather than the block
layer.

Also, media change is another thing that you may want to be informed of.
The qdev device and the backend stay the same, but the file name
changes. We have notifiers for the device emulation on media change, but
we don't have anything for the UI. (Or can the UI use QMP events?)

If we need something, we can probably add it, though.
