Whatever the merits or demerits my suggestion would be that hired gun programmers learn to deal with databases like the ones you describe. In my experience they are ubiquitous and one needs to be able to program against them and submit scripts that honor the prohibition against nulls.
I know that in the hundreds of tables I deal with every day in dozens of databases in a fairly large enterprise there are no null columns in production, period.

- Thomas Hardy
Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.

Pardon him, Theodotus. He is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
