Back before ED was a reality there was the DDF. One of the topics up for debate during design was in-system travel.
The original proposal was very, very similar to hoe Start Citizen has implemented things, you would make mini jumps in system, so think of a system as a set of rooms. When you arrive in a systm, you would arrive at the Nav Point in a system. This was actually the original purpose of the point, and was supposed to be a dangerous place as you had to go there, and pirates and bounty hunters would hang out there.
Anyway, us old ones in the DDF that remembered Frontier and First Encounters wanted in system travel similar to those game. We obvioulsy argued well, as the original proposal was dropped for what we have now. So its a case of blame the KS backers, I am not sure it can change now, as othe game mechanics have morphed to meet the new movement mechanic. The one area that has really suffered is Bounty Hunter, Pirate, Trader interaction, or the concept of safe Nav Points and not so safe nav points is all but gone.
I actually like the travel, and using curves to speed things up etc. However I can see why those wanting a more action packed game can see it has dead time before the next bit of the game starts.
