Once they reach stage 3, new language features are initially implemented behind a --harmony-* flag. Your proposal boils down to simply keeping this flag around forever, for this particular feature.
By the way, this would be good feedback for the proposal champions. Please post it on the proposal repo <https://github.com/tc39/proposal-function-implementation-hiding/issues> if you haven't already. Thanks!
