It's not only about securety. It's about the "C" in "ACID": Consistency!
Example:
mysql> create table test (i1 int, i2 numeric(6,2) not null);
Query OK, 0 rows affected (0.01 sec)
mysql> insert into test values (12345678901234,123456.23);
Query OK, 1 row affected (0.01 sec)
mysql> select * from test;
+------------+----------+
| i1 | i2 |
+------------+----------+
| 2147483647 | 99999.99 |
+------------+----------+
1 row in set (0.00 sec)
I think I would call this.... inconsistency!
You can't just put any data in the database if it doesn't comply to the
structure of the table. But that's how MySQL works. If you try to insert a
negative number in a int unsigned field it won't give you an error. Instead
you get 0 (zero). This is totally unacceptable, at least from my point of
view.

I think just like you in this case.
