Weird. AFAIK 4K and 64K were the common ARM64 page sizes, and 16K was the odd "think different" one that Apple uses. No mention of 16K in the Linux kernel docs:

64K starts to be a little too wasteful. It is a small performance gain as you'd expect, but less granularity means significantly more wasted memory

On a phone with limited RAM, this starts to be a bad tradeoff quickly. 16K is a reasonable jump from the venerable 4K page size.
