One of the advantages of the Apache license LLVM has now moved to is
that it provides a clarity on issues such as what represents a
"Contribution" (defined in section 1
https://www.apache.org/licenses/LICENSE-2.0). I take your point that
being innovative is undesirable and see the advantage of following a
well-trodden path, but I do think it might be worth looking to take
advantage of these clearer definitions in the future (even if not for
this instance), getting confirmation from lawyers as required.
