Circa 1970 and earlier, 15T small cogs seem to have been much more common. My 69/70 Raleigh Pro Mk I came with a 15-30 FW, which the Campy NR RD shifted OK. We sometimes forget it isn't usually an absolute limit as to how low a gear one can use, but rather how wide a range. At the recent death of the famous round-the-world cyclist Ian Hibbel, I read some articles about his exploits, complete with photos of his bikes. I had either forgotten or never noted In The Day that he actually favored the Campy NR RD, and perhaps earlier the old Record. This sounds impractical for loaded around the world touring, but the key is he used FW cogs no larger than 15T and small outer rings, 48T or smaller I think. That allowed him to handle a pretty low gear with a Campy NR, by giving up top end to gain bottom end. For actual racing, a few may need that 53-11, and the average racer maybe a 53-13, but for any other application 50-14 or even 50-15 is quite adequate and allows a lower low gear without going to a long cage RD.
