You don't say which BSD, nor which version; there is no single "BSD's
setitimer manpage". But at least some of the BSDs run on hardware that
simply cannot do what you suggest.
Unless you think they should install a different setitimer manpage
depending on which hardware is in use (which has its own problems,
mostly involving human expectations).
