What does it mean if you have NULL for the new field? Does that work, even?
If it means there is code in a .c too handle it there, we should use that
*always*, not just for a few entries, since it simplifies things.

Maybe? I'd like to see a design for it. Historically, tweaking this stuff
has been very error-prone.
