I think it is appropriate. The actual work and scope may need to be
refined a little more, based on what you find is already supported vs
what does not work. But, to get a suite of llvm/clang "recipes" in RSB
to build targets is a good first step, and then adding some of the
sanitizer/fuzzer on top is a great extension.
