You've been able to do it since (insert google search) the addition of Utopia in 2017. Basically there are a few L-gates scattered around the galaxy and you need to get 7 mcguffins via research/exploration and the first person to get open them, which triggers a minor galactic crisis.

When you actually get it in there are a few versions it can take but all basically involve a slightly weaker than fallen empire level story faction that continuously spawns nanite battleships and the worlds all have unique buffs that make them really strong but they all have to be terraformed with a unique nanite cleansing tech. If you are the only one who gets the L gate tech you can use the bottleneck system at the front as a super fortress and its so far from the rest of the galaxy you can never back door the rest of the systems. Additionally, you basically get a bunch of indestructible gates only you can use all over the galaxy, so its really strong for raiding. If its super late game you can also build your own gates, connect them to the L gate network by building a gate next to any L gate and now you have beachheads everywhere from your home systems.
