There's no implications at all.  Hyperspace Beacons, Runs, (Like the infamous Kessel Run) are all well defined.  Sure, the vessels can move at supraluminal speeds but they do so blind and could slam into stars and black holes and who knows what else.

Despite their likely being millions of habitable worlds across the galaxy only a small percentage have been discovered and mapped out.  Hyperspace travel is done mainly via Hyperspace Lanes, well traveled and mapped routes that are deemed safe and, usually, are lined with beacons.  

These lanes, the known worlds, and the lesser routes were mapped out via sublight probes and insane explorers making small micro-jumps.  This is why the Empire plots all known locations along an escaping vessel's trajectory.  Smugglers collect and trade secret hyperspace routes, using them to bypass imperial blockades.  Rebel Bases could be right next to a major colony or within the deep core but completely undetectable if nobody knows the secret route to get to the planet.  It also makes for "choke points" where fleets can defend various systems since, in order to get to a certain Solar System there are only so many ways to get there.

In the Revenge of the Sith, the Separatist Fleet manages to bypass the entire Republic Fleet and kidnap Senator Palpatine before anyone has a chance to react because the Separatists discovered records of a lost Hyperspace route that served as a back door into the Coruscant System.

I liken the system to the old Naval Concept of "Reuters".  Before the invention of the sextant sailors couldn't reliably place themselves on a map.  Thus Reuters were log-books that included every move a ship made on a journey.  That way if one left at the same time of year and followed the instructions there was a very likely chance they'd end up at the same place.
