Comment (by jdgrimes):

 Thanks for taking the time to do some more research, @tyxla. I realize
 that this won't affect the `get_row()` calls, I just wanted to document
 that because it is related. I wanted to see if there was any pertinent
 discussion regarding `get_var()` in the corresponding ticket, but as I
 said above there wasn't.

 I think this would be a good change—I just wanted to see where the code
 came form and whether there was any reason for it.

 It's possible that there are plugins that are relying on this behavior,
 but even so, I'm not sure that the change could really break anything
 badly. I guess that's something we should still consider though.
