I'm not apologizing for their past mistakes.. But the issue
you cite is no longer true:

"As of 5.0.2, the server requires that month and day values
be legal, and not merely in the range 1 to 12 and 1 to 31,
respectively."

mysql> use test
Database changed
mysql> create table test ( td DATE );
Query OK, 0 rows affected (0.01 sec)
mysql> insert into test values ('35-Feb-2007');
ERROR 1292 (22007): Incorrect date value: '35-Feb-2007' for column 'td'
at row 1
mysql> select version();

The only reason I'd need is that MySQL (even InnoDB) lets you
accidentally insert intrinsically bad data. According to the
official v5 docs, it's the app programmer's fault if s/he tries to
insert 35-Feb-2007 into the database. MySQL will purposefully
convert it to '0000-00-00'.
