> Credit card entry

If you're handling credit card numbers yourself, you're in a shrinking subset of developer roles. I've spent the last 7 years of my career working at payment processors, so I do handle that stuff, but the majority of my industry has built an infrastructure that makes it so most developers don't have to think about that.

To your other examples, not everyone on the team needs to know these things up front. Someone in the review process does, and eventually that knowledge gets disseminated and more people know it to carry it forward in their career.
