Beyond making this like other vir.*ObjRemove APIs, no and fixing what
would be an "obvious" coding error.

I suppose the argument is that the driver/test lock wouldn't allow
change to the list so true technically it doesn't matter. I can drop
this if that's what you'd prefer.  Eventually it goes away completely,
but that's code I have in my branches.
