I don't care if devs understand IP packets, TCP congestion control algorithms, or anything similarly low-level. If they do, that's awesome, but it's not expected. I do expect them to have a basic understanding of expected latencies for intra-DC vs. internet, why running Flask in production isn't a good idea, and if they're really sharp, an inkling of how Kubernetes networking works.
Why do we call these people "software engineers" if they're not engineers. There is endless documentation, there is all the resources needed. Allowing devs not to know what they're doing is a complete failure of anything approaching professionalism.
the flask build in webserver is not production grade software in my opinion.

I don't expect junior devs to have a sense for what is production-grade and what is not, but if they try to ship software that explicitly warns against being used in production, you've got a real liability on your hands.
