>In the near future, we will see some cores that don't support 32bit arm code at all.
We already do. Lots of them. Every iPhone since the iPhone 8. M1 and M2 Macs. ThunderX in server farms, Cortex-X2 and Cortex-A510 cores in your high end 2022 Android phones (Galaxy S22, Xiaomi 12 etc). The Cortex-A710 cores in those phones do still run 32 bit code if needed.
ARM has said all new applications processor cores from 2023 will drop 32 bit support.
