i see your point of view. however the only time you get real advantage with building large off platform is before you activate the warp mechanic and after you extended time to like 30 minutes. by the time you reached that point your platform should already be big enough to do all the essentials anyway.. maybe not on a large scale, but without enemies you wouldn't have the need to build large anyway since time is fully on your side.
another possible solution would be to limit the build area around the platform for buildings to a certain range (belts, pipes and power poles excluded) and create like a small area around resources like oil. just a suggestion.
i understand the low priority, but would love to this happen somehow.
