Found this in gnome-session:

/* These are variables that will not be passed on to subprocesses
 * (either directly, via systemd or DBus).
 * Some of these are blacklisted as they might end up in the wrong session
 * (e.g. XDG_VTNR), others because they simply must never be passed on
 * (NOTIFY_SOCKET).
 */
static const char * const variable_blacklist[] = {
    "NOTIFY_SOCKET",
    "XDG_SEAT",
    "XDG_SESSION_ID",
    "XDG_VTNR",
    NULL
};
