Block driver "raw" forwards most methods to the underlying block driver. However, it doesn't implement method bdrv_media_changed(). Makes bdrv_media_changed() always return -ENOTSUP. I believe -fda /dev/fd0 gives you raw over host_floppy, and disk change detection (fdc register 7 bit 7) is broken. Testing my theory requires a computer museum, though.
