The arm spec allows to have machines that implement any of 4KB, 16KB, or 64KB granules or any combination thereof. Apple shipped plenty of phone SoCs that didn’t support 4KB pages for the CPU (A9->A13).
Interesting - at first this didn't seem to be detailed in the popular (Wikipedia etc) or ARM web pages I could find but it seems it was about terminlogy, "translation granule" was the right one and then you can find mentions like "The granule sizes that a processor supports are IMPLEMENTATION DEFINED".
