I agree with your point 1 and half of point 2 of your response, however, unless both start and house banks are completely isolated (which in most cases are not) it's better if the batteries are rated the same. Once you start adding external charging sources IE solar, it only takes a short time for the start battery to get cooked if not switched or correctly isolated. There's been many a posting here ( perhaps hundreds, even thousands) over the years with battery/charging issues suggesting there's obvious issues with the way many boats are wired. Keeping the ratings the same prevents over charging of the lesser battery.
