That, plus a way to specify that a race would get ships to start with (and no planet), and probably a way to specify that a race awards certain specific tech at once, too. A ship-borne race has a LOT of problems to deal with, such as resupply (they'd need either some solar collectors, or perhaps a large engine that doesn't need supply (or maybe small, but only providing bonus movement ala a Solar Sail))... they'd need to start with a shipyard ship as well, or have a way to get one.
