Actually not all. Some Peter Mooney frames (and most proper touring frames) utilized two points of rack attachment to seat stays even back in the early 1980s. "Sports touring" frames did however use a single brake bolt attachment, and there were a lot more of them sold than pure touring bikes, much like today.
True. I forgot about my old Miyata 610 with the factory installed rack. Probably because I never put it on nor took it off.

They are way easier to use.
Alternatively, you only really need one of the rack stays anyway, especially if the stays are the round type like the ones found on Tubus racks. The left side stay interferes with the brake on my wife's tiny bike, so I just use one on the right side. Works perfectly.
You can see the same thing on my Moots, although I had to twist the stay around more to get it to fit.
