While a perfect justification for a lot of TL5 planets, I view something like a nonindustrial agricultural TL10 world with grav harvesters as a statement of economic export clout.
The planet has enough profitable exports to afford importing the good stuff, so we can expect one or more high value crops or dependent meats or animals and they are amenable to automated equipment, especially being a low pop world.
Or the high tech allows freshly harvested preservation that increases shipping value.
