If you expose it to userspace then you would want it very tightly controlled and very much special case. Within the kernel using it internally within things like CMA allocators seems to make more sense. I think you overestimate the abuse. It's an interface which pushes clean pages that can be cheaply recovered out of memory. It doesn't guarantee the caller reaps the benefit of that, and the vm will continue to try and share out any new resource fairly.
