Actually it is "level=vbackup".

Yes, that sounds reasonable.

Anything is possible.  I previously asked for suggestions on what directives 
to use for this, but didn't get much, so I have started something very simple 
and brain damaged, which should handle most of what people want.

If users want/need virtual differential backups, we could probably invent

level=vfull

and 

level=vdiff

but I am not really sure of its usefulness.
