Necessary depends on many things, divers were once water people, people who lived on and in the water, fishing, boating, working, whatever and were good swimmers, divers now, mostly cannot swim, they need a life jacket...
People who are obese/out of shape divers, which is about 75% of divers, need many aids to offset the fact that they are essentially disabled, and people largely today feel that safety is a right they were born with and again, that thinking simply does not apply to many of us from previous generations.
