The spaceship floor hack is interesting, though I wonder if perhaps that's sort of going against the spirit of the mod. The idea, at least how I see it, is to separate out space / planetside processing and require transportation logistics to assemble stuff, utilizing prod mods in one place, and speed in the other. It feels like something that should be nerfed, imho.
Also, one might imagine that the space machines are meant to work only in zero g or close to it.
