B) The liner system remains as it is for ID/usage purposes. They are given a buff (Mjolnir permitting) and are hooked (Cannon permitting) to only permit a certain degree of non human cargo.
Though along with this, I'd like to see some more generic people-centric mid-sized transports. Or one. Like the Geisha, but more generic, and also with the hook. Or maybe buff the Armored Transport.
My thinking is that most corporations and many unlawfuls would want to move people but not use a fancy luxury liner type ship. For example, many Junyo workers live on Deshima and many miners and such live on Sheffield. Getting a ride to work would be nice.
