Afaik, openmp is available on windows. According to writing R extensions: There is nothing to say what version of OpenMP is supported: version 3.0 (May 2008) is supported by recent versions of the Linux, _Windows_ and Solaris platforms, but portable packages cannot assume that end users have recent versions. OS X nowadays uses clang, and the Apple builds currently have no OpenMP support.
So I take that answer as, "No, CRAN cannot possibly enable openmp for binary builds." Is that correct?

Many CRAN packages offer improved performance when compiled with
OpenMP. However, the MacOS and Windows binaries built by CRAN are
built
without openmp enabled. Would it be possible to build openmp enabled
binaries for some CRAN packages?
