That might at least give some incentive to those running GIGO-excreting computer systems to clean up their sh*t.
> “null” is also a text string that in many programming languages signifies a value that is empty or undefined.
I can't think of a single language that does this. A null interpolated into a string or concatenated with an empty one could produce such a string. If that string value is then used to signify an empty/undefined value is misuse of the language.
Although I suppose it is an edge case because NULL is supposed to not ever get joined with an address or UID.
