Seconded...I swear to God "that's a symptom of bad design" and its ilk are the most hackneyed type of response to a situation that has the bonus of making you seem "above it all". It absolves you of even having to bother to look into the situation to see if maybe there is nuance that you can't just throw platitudes at.
I asked for how this PEP could or could not be used for my use case, and your response was "your use case is invalid" without knowing why I do the things I do. No one should have to respond kindly to bullies.
