The reason is that FreeBSD refcount.h shadows ZFS refcount.h and that will lead to a build error after a planned import of the ARC buf data scatter-ization. It's possible that some day we will have an opposite problem where a ZFS header would shadow an essential FreeBSD header. So, we need to think about a better long term solution.
