Comment:

 I agree that this meta box is terrible and that the general goal should be
 to remove it entirely, but I think in the meantime, a short-circuit is
 smart and the idea of populating the dropdown with values that aren't
 necessarily existing meta keys is a pretty interesting one. I wouldn't
 advertise that as a good use, though, since we don't want to actually
 encourage using the default meta box :)

 Strongly agree about using `null`. Going to commit this as a fix for 4.4 -
 longer term we shouldn't have the meta box registered by default. Not sure
 what can realistically be done about the actual underlying DB problem.
