This is false. There are some mission that they can not fly yet but the additional capabilities for the upper stage are already in development and have been partly tested. I would expect that by the time the FH flys the upgrades to the upper stage should be rolled out, so they can fly direct insertions. There is still the additional problem of vertical integration. SpaceX will start doing that on pad 39A.
