I think the question was, can they write their own backend for LLVM (a
new Target) and will their code automatically work with future
releases of LLVM.
In that case, the answer is yes, you can develop your own backend, but
no, LLVM does not provide API stability. As new versions of LLVM are
released you would have to update your code to the new API or stay
with the old version of LLVM.
