I'm not sure that that will make a difference, though. MySQL will see NULL,
perform a string-to-number conversion and end up with a value of zero.
And inserting 0 into an AUTO_INCREMENT column should be the same
as inserting
NULL. Still, it'd be worth a try to convert

You're both wrong. You should test it, and see for yourselves that

auto_increment values are NEVER reused. This, of course, is true if
the auto_increment is on the first part of an index, and you don't
