Yes: we want to warn folks early. This is just warning them, and they can opt-out. Getting it in the release branch is exactly the right place: people try out releases much more than tip-of-tree.
We want it in LLVM 8 because then there will have been enough advanced warning that, when we're ready to move away from C++11 we can do so. Tentatively, the target is end of the first quarter of 2019, so right after LLVM 8.
