That wasn't in the original comment. It has been edited since I replied, which is fine. I do it all the time, sometimes you miss that someone replied during your editing.

Similarly, it's not good teaching practice to trivialize deadlines.

Yeah plenty of time for workplaces to do that for you. I can count on my hand the number of times something has been a hard deadline. This teacher taught a valuable lesson usable for the rest of the student's carreers and "the most students shouldn't fail mentality" has led to professors I know personally questioning the caliber of student they are receiving and this is a top 30 program I'm referring to. More people should fail, maybe they'd start treating things seriously and the problem of underqualified technical applicants would resolve itself.
