Pretty interesting... I really feel like I'm on Ben's side of this. Using higher-level libraries to simplify ideas and claiming that real bugs are out of scope are both things that might sound good on paper but are likely to cause harm in the long term.
I'd rather be overtly honest about the nuance and potential pitfalls that come along with building even a super simple app. HTTP timeouts are important, concurrency needs to be safe, user input must be validated, etc etc. I don't think it does anyone a favor (especially new devs) to hide these details. Put them out there with well-written descriptions and explanations.
