Context: LaTeX is a typesetting system. When compiling a document, a lot of really in-depth debugging information is printed, which can be borderline incomprehensible to anyone but LaTeX experts. It can also be a visual hindrance when looking for important information like errors.
Those template errors feel almost passive-aggressive to me. Almost as if the compiler is telling you “Here are all the ways in which I tried to make your shitty code make sense, and yet it still doesn’t work” lol
