There is no evidence for -machine, -accel or -object.

Notably (and for Libvirt only):

- '-object' takes a detour through JSON, and uses sometimes =on/=off or 
 sometimes =yes/=no.

- '-accel' is not used at all

- '-machine' does not use short-form boolean options by sheer luck.

The only known usage in Libvirt, for instance, is for "-chardev" and "-vnc".
