The mere fact that something is requested does not imply that the request
should be accepted. I'm sure there's a name for this fallacy, but I can't
think of it just now.
This is especially true when the common request stems from common ignorance.

This is why the request should be rejected. NULL has a specific semantic, and
it is most emphatically not the same as an empty string.
It is not wise to mess with the fundamental mathematics of SQL. Get used to
the fact that NULL is not empty string; embrace the fact and learn to love it.
