The bus value can be retrieved indirectly from the class hierarchy. 
Aliases are deprecated.

Desc could be moved to the object class and added to qom-list-types.

Indeed.  The question is why they need "-device ?".  If it is just for 
"is the device supported" (as was the case for libvirt before it started 
using qom-list-types), then a new command is unnecessary.
