As I said in the discussion about similar flags for GVN, I'm generally fine with. We should have a big fat warning in the Release Notes that all -fexperimental-* flags are exactly that -- temporary and not intended for long term consumption. I.e. "we can and will remove them whenever it creates the most havoc".
