FYI, Android enables 16KB page size now: https://developer.android.com/guide/practices/page-sizes. 
Currently there is a strong push for adoption in mobile / client devices for RISC-V. Android enabling / moving to 16kb will create pressure for RISC-V to also support similar features. This will create a strong push for RISC-V also adding support for larger page sizes.
