You're being polite using the word "old school" on someone who doesn't have the sense to feed different-sized dogs different amounts of food ... IMO different terminology for this would be more accurate ... but it only confirms my impression.
I realize there is a lot of "general respect" for some of these old-timers, so I will leave it at that, but I've met enough of them to realize that many really just got famous cause they got their hands on some good dogs.
