I think what I intended to get across isn't too incompatible with what you're saying. I think it's fine to say "this function is too long", and long functions generally speaking should be something that's worthy of a code review comment. I think the issue that originally launched this thread of the discussion is people who take the specific rules to a dogmatic level and apply rules blindly, and transform "functions should not be long" to "functions should be less than 20 lines no matter what". 20 lines (or whatever standard you land on) should be a guideline and not an inviolable law of the universe, and if reducing a method below 20 lines harms comprehensibility and readability, you're letting the guideline get in the way of the actual goal.
