Hm, I not sure about this one.

You might just add a parent itemtype for testing, the only purpose right now is
the max checkouts, later decide to remove it... It's not a required/mandatory
field, so I'd day NULL would be ok, maybe with a confirmation warning in the
GUI.

This way you need to remove it in all itemtypes first, more clicks, but I can
live it, just think the other is nicer :)
