Are city blocks obsolete with SA?

Basically the title. I was designing geometric city blocks with a different shape for each planet (obviously super late game with loads of foundations) and then I realised that a couple green belts with 4 high stacks can accomplish so much more than a train can in terms of item transport. I feel like the new buildings are so good that there is no need to build crazy huge bases anymore since everything can be condensed down so much now
