It is not *my* goal, and it is used here to steer people away from
working on Semantic's C++ parser, saying it is pointless if it can never
do refactoring, which is a *much* harder problem than providing
completions. I don't see the point in discouraging people like that.

Anyway, Stefan gave is OK on libclang usage, so the initial problem that
started this discussion is solved, and I suggest you start hacking.

As always: unless someone starts working on these things, nothing will
happen, and surely nothing comes out of those centi-threads we seem to
have every month nowadays.
