We find the ability to add a FK constraint without validation very
useful. We have added unvalidated constraints to a couple of tables so
that all new data has to pass the FK test while containing data
retrieved from a legacy mainframe system that sometimes does not meet
the tests. This has allowed up to tap into history going back over 20
years. Having online access using the current sytem without
modification has proven very useful to the customer.
