"Half of all developers have below-average diligence" - a lot of this is also not developer choice, but environmental. So much software is developed and maintained in very constrained economic environments, often by solo devs who also have other responsibilities. The choice here often is trading some "diligence" for "meeting business requirements in the time / budget constraints" imposed by your employer.

Absolutely true, but still indicates the need for tooling, for automation, and for oversight at the the package store.

"developers, be more conscious" isn't going to fix all the issues. In general, there are not individual effort fixes to systemic issues.
