Completely false. The 4 KiB page size came from a machine with a total of 512 KiB (1962 Atlas, 3072B pages, 96k 48b words). It hasn’t scaled at all for inertia reasons and it has real and measurable costs. 64 KiB would have been the better choice IMO, but 16 is better than 4.
Hence the "minimum" part. The thread is literally about Android being compiled for 16KB pages, CPU support for larger pages has grown, easily up to 4MB for most consumer CPUs.
Going down _lower_ than 4KB is purely a waste of memory and performance.
