The wording is along the lines of, the divers need to be certified for the dives being undertaken.
How you interpret that is up to you.
I think this is a key point. Many people, especially longer-term divers, may tend to interpret that as an open water diver certification is a recreational scuba diving certification, with recreational diving covering depths down to 130 feet. That does not mean someone fresh out of OW training should immediately dive to those depths, anymore than a young drive who just got his driver's license ought to go drive in demanding congested urban road environments. He should get additional experience and grow his way into it. This is how things used to be.
For comparison, getting a driver's license (which if anything is a bigger issue since more people drive solo and accidents are more likely to kill other people) is, for non-commercial car and truck drivers (I'm not up on motorcycle requirements), largely a one license thing.
We don't start with a basic driver's license that covers the countryside and small towns, an intermediate license for somewhat congested areas in cities with populations up to 200,000, then an advanced driver's license for major metropolitan centers.

3. The Advanced Open Water certification was created by the Los Angeles County program in the mid 1960s to introduce divers to a variety of different aspects of diving in the hope that it would improve the low rate of diver retention. NAUI followed suit. PADI did not add AOW until later.
Notice that the course was not designed to certify people as safe to dive 100 feet (you can get the PADI AOW cert. without going nearly that deep, unless things have changed). It doesn't prove they've dove to 100 feet deep, much less that they've mastered the knowledge and skills involved and are safe to do so.
None of which changes the fact insurance operators can demand divers do most anything not illegal as a condition of operator coverage.
P.S.: It's interesting jumping thread to thread. One thread decried a Malta court finding of dive buddy liability thought to be ridiculous. Another on the
Conception disaster brought up the issue the rec. diver community has been anti-government intervention but now some wish the government had 'done more' to prevent it. In this thread, liability risk-ridden operators have trouble finding insurance coverage and start requiring a certification not practically necessary, designed for or reliably serving the purpose, because it'd look good in a lawsuit.
