I can't speak for everyone else, but I'm guessing it just sounds too much like an idea "stolen" from another franchise. Elite is more less the grandfather of this genre of games, and none of its titles had jump gates. It places more importance on the ships themselves, and the engines they carry.What's the problem with jump gates?
I'd rather see further customisation regarding the ship's equipment (which is coming), as well as the option of having a ship ferried to a different location (which is coming, for systems that already have a starbase), and possibly a way to store a smaller ship in the hangar of a larger ship (aka "pocket carriers"), allowing for multiple explorers to band together with a small flotilla of specialised vehicles.
