First, I think clang-refactor is a great idea and a great point of focus for really useful tools.

As a maintainer of a code comprehension tool which uses libclang, it would be really useful if such a refactoring ability was exposed via the higher-level APIs. We’d *love* to have IDE-like refactoring for C/C++/etc. in the tool, and I’m sure our users would too :).
One of the challenges we have with clang-rename, clang-include-fixer etc. is that they are difficult to integrate with existing applications which use libclang. Or perhaps I should say, they require orthogonal integration - currently to integrate these tools, even though I have successfully generated a TU/AST etc., I have to shell out to a binary which users may or may not have installed.
I know that is probably complex to deliver in practice, and I understand that the maintainers may have different opinions on the scope of libclang (or even the scope of this discussion!), but I wanted to throw the idea out there, in case there is appetite. Certainly, I would be super excited to integrate these tools into ycmd/YouCompleteMe. I don’t doubt others would similarly benefit.

Me too! Thanks for the work and ideas.
