How "restricted"? You haven't provided an example of information that
cannot be modelled without nulls (because no such information exists).
If you just mean "complex" or "difficult" then say so - I don't really
have any more to say on relative complexity than I've already said.
"Restricted" implies that the model without nulls has limitations but
you still haven't explained what they are.
