Legend can be located outside the plotting area, anywhere you want.

Good to know.It is a bit more complex than a legend inside the axes though
as you need to setup a bbox.
btw, there's a typo in the html page: should be bbox_transform instead of
transform in the doc:
"For example, if you want your axes legend located at the figure corner
(instead of the axes corner):
l = legend(bbox_to_anchor=(0, 0, 1, 1), transform=gcf().transFigure)"

If there is a single non-keyword argument, it is treated as a list of
labels.
meaning that you always have to fully specify the labels.

To me, the current behavior seems reasonable. What do you expect?
An empty square isn't terribly useful and will likely need to be hidden.
Could this form be used as to simply get rid of the legend instead ?
