My sister would disagree with your assessment, and she's been a diabetic since she was 4 years old(31 years of shots now). If my great aunt was still alive, she'd be jumping for it too since she'd been a diabetic for ~70 odd years. There are plenty of methods to avoid hypoglycemia from working out, this in itself is a huge step in the current pump a needle in you every 2/4/6/8 hours that exists now.
The biggest problem is with kids and getting them to do monitoring, tests, etc., since many of them don't understand not doing something like that will kill you. It's a concept that a 4 year old can't get, no matter how simple you explain it to them.
