Wing Commander 2 was the last (?) game where tankers are evident. They are also the last game without evident ramscoops on the majority of the ships (the Gilgamesh has some over-wing ports with red dots that seem similar). I know from fiction (End Run, Fleet Action) that ramscoops were common prior to the battle of Earth and were equipped on small patrol craft such as Ferrets. Do we know if there is a (deliberate) correlation between the lack of tankers and the visible ramscoops, and what the purpose of a tanker would be if even small craft could scavenge their own fuel?
