But also speaking of the iPad Pro, would Apple really cut off the entire A12 era at once?
I don’t think Apple will cut off the 2018 iPad Pro, given that the 2020 iPad Pro uses identical hardware, other than one GPU core.
iOS 8 and 9 had the same support list, as did iOS 11 and 12, 13 through 15 and 17 and 18.
It makes sense to me that 26 and 27 would have the same support list, iPhone 11 and newer, before next year, where absolutely everything, iPhones, iPads and Macs alike, are A14/M1 Firestorm and Icestorm cores and up.
