Mariusz, I agree with the burden, but it should be noted that SQL has both CHECK on the field and table level, and CheckConstraint only defines table-level constraints. This is not true for unique constraints or indices.
Also, what do you think of a way for custom field classes to add constraints, at least? db_check() is somewhat limiting given it must return raw SQL, plus it's undocumented.
