I too prefer to keep it turned off in 9.6 and consider enabling it by
default on a future release (10 is probably good). Interested users can
carefully test the feature without endangering other unsuspecting users.

I agree with the idea of keeping it enabled in master, so that it'll get
a modicum of testing there by hackers, too.
