And virtual disks are copied to new disks as expected for a clone. Only the
disk device content isn't copied.

Imagine there is a device with 4TB mapped to a guest. There is no possibility
to copy this huge amount of data. When people do disk device mappings, they
know what they are doing, so indeed they know that a copy will reference the
same physical disk.

What would your proposal to clone/copy the device data?
