It did occur to me that with the galaxy now divided into 42 regions, a Guardian jumpgate, or a wormhole, concealed in each region waiting for us to find it might be a thing.
It might be time for a development like that. Let's face it, with Exploracondas now capable of better than 4,000 LY/hr even without using neutron stars, merely travelling long distances isn't the challenge it once was; it's just a bit of a time-sink.
The challenge in exploring these days is in getting to difficult-to-reach places, and jumpgates wouldn't affect that. And it would open up destinations in the whole of the galaxy for Frontier to plant new stuff, if they were so minded.
