One reason to have the API take values in KiB could be to avoid having to deal with 64-bit values, which could unnecessarily bloat the code. I've made several mistakes when dealing with KiB values, so I think using values in bytes is a good idea. Still, I believe that changing this API in a single commit is just unreviewable, and I'd much prefer to have these two APIs coexist for a while.
