I think the right question is whether that license meets Boost requirements on license. To
the best of my knowledge, there's no requirement that Boost compoments use BSL.

It appears that this Boost requirement:

        Must not require that the license appear with executables or other binary uses of the
          library.

directly contradicts LLVM's license.
