If we can load starships into transports now, does that mean we can load other things as well, that we couldn't before? Like the Advanced Science Lab?
The advanced science lab is the slowest science lab, but it also has a good deal of HP and can collect knowledge in systems that are out of supply. Normally its speed of 8 is too slow to do this, but you could pack it into a transport (along with warships to provide cover), send the transport to a planet just out of your supply, and do knowledge raiding that way in a system where it would normally not be possible. Transport loses some HP, sure, but it still has 2/3 of its health left. (Bring alone spare, empty transports if you think you might lose a few to AI warships)
