That sounds like I'm being a troll. (particularly since I was just
arguing that null != empty for string_ref.)  Maybe it would be better
as:

Is there a difference between empty and null?  Probably.  Is there
commonality between empty and null?  Probably.  Are there important
differences in this case, and/or is optional's
flexibility-of-perspective a feature?
