The distinction here is between code thats clear and concise or code that hacky and confusingly compact. Few people would recommend try and pack a 4-5 line function into a super complex and confusing one liner, but it is reasonable to put a 10k line class into a 20 line function. It's on us, as the developers, to make that tradeoff.

I think the spirit of the comment you replied to was closer to the "clear and concise" methodology rather than the "as short as is humanly possible" methodology.
