The focus of the linked article is responsiveness/user interaction, attributing that to efficiency cores. Apple can achieve exactly the same responsiveness benefit on their Intel devices by, as mentioned, limiting low priority tasks to a subset of cores. Say 2 of 6 real cores on a MBP with an i7. Apple actually pushes low priority tasks to the efficiency cores for power efficiency reasons (per the name), not user responsiveness. So that MBP runs for longer, cooler on a battery because things that can take longer run on more efficient, slower cores. They do the same with the efficiency cores on modern iOS devices. The "feeling faster" is a side effect. I am talking about that side effect which isn't ARM specific. And FWIW, Intel is adding efficiency/"little" cores to their upcoming architectures. Again for efficiency reasons.
