We have used deferred constraints a few times instead of immediate constraints.
But only because the logic could be violated during the transaction. The main
thing is to remember that in case of deferred constraint violation all
transaction will be rolled back, not only last statement. Sometimes it matters,
especially in case the transaction is big or logic complex...
