If anything, it should be an error to access $_ SESSION if no session is currently open - if there is no session, the array has no meaning. (Arguably, all the other superglobals should be read only for the same reason, but that would be a huge break now.) If I understand you right, the scenario you describe is "I don't want to start a session yet, but if and when I do, I want to put this data into it". It feels like that could be adequately handled in userland with a wrapper object (or global var and functions if you prefer), which reads to and from $_SESSION when a session is open, but a a holding array when it's not yet.
