If you assume that there is a civilization that has gone to the trouble of developing interstellar transportation, I think you can assume they value the differences between different parts of the universe. Considering that inhabited planets or even solar systems seem to be much more rare than uninhabited ones, I don't think it's unreasonable to think these difference-interested beings would want to stop by to at least map out an inhabited planet.
