Only the superliner is planned to OSC restricted the rest of the line woud probably fall under the civilian techcell and be open to all.
Keep in mind that throughout the mod's history OSC has had no new ships added to it, we've adopted two yachts into our usage but the two old vanilla models are the only thing credited to our faction (Enterprise and the Prison liner, which is itself an older liner). whilst several imported or made up factions have received entire shiplines.
