Jeb would still be just returning from his second mission to Jool if KSP didn't have 10000X time compression. But KSP also has a gravitational/orbital mechanics, at least a couple of versions of Alcubierre drive from user built mods to make long distance travel more enjoyable without speeding up the clock. That might be a way for CIG to introduce interplanetary travel. I'm not sure why we need jump drives to fall into a wormhole though, so they could be re-purposed for interplanetary missions, instead of interstellar. Unless the jump drive is the way to get to the jump gate, in which they already have the mechanic, it seems to me there's a gap somewhere.
Thing is, to me SC is (or will be) a sci-fi game (depending on your perspective) so CIG can do whatever they like if it has a good back story, and awesome graphics, especially when my Aurora blows up yet again. Some players will complain no matter what CIG does. But most players won't complain too much. What they'll do is concentrate on how to leverage the game play mechanic to their advantage. Then, nothing stops CIG from releasing additional updates to SC that evolve gameplay over time.
