There is no foolproof way since SET IDENTITY INSERT ON will allow reuse.
You could leave the records in place, using a deleted flag column to
indicate a logical deletion.
You could use an insert trigger to intercept id's that are below the max(id)
value.
You could use stored procedures and permissions to block the usage of the
identity insert.
