It didn't get turned on by default simply because it hasn't had enough
testing, so we're not sure that we've got full coverage for all the old
functionality.  The great majority of stuff certainly works, and we'll be
turning it on once the unstable tree opens for business again, so that we can
get it more widely tested.  It will be the default in the next release.
